The approach on this PR moves around refactoring/ updating residual work; main issue was the whole logic behind msaa upload/download images with the constant image copy per pass required; which was gated via shaderStorageImageMultisample, which is not available on all the platforms supported including Android, making them to rely into a more heavier approach to convert msaa image copy into a non msaa image copy, not only losing precision in the conversion, but also creating bugs around the resolve of the image itself, if the supported path had to copy 2 times the same image to be actually presentable, when the fallback was enabled 3 copies were performed, not only decreasing the performance but also increasing race conditions due to the certain capabilities processed in this chain (storage_views). In order to resolve them more naturally, the constant copies were removed from the now "common" path along establishing a proper color resolve for Android and actually making them more direct.
Yet this opened a new pack of outdated handling on our current backend; since we now pass msaa images more directly (whenever a game request a msaa type of image/ which seems to be not common + each fragment resolves images on how it's actually required, adding missing depth/stencil), how we often load and store them becomes a critical issue, since our current configuration renderpass/framebuffer forces to always load and load clear whenever a new attachment it's passing through the renderpass, making this really heavier on memory bandwidth limited devices as SteamDeck and others that doesn't rely on the inmediate rendering mode (Tilers vs iGPU); to prevent over allocating data, I had to re-structure part of the current renderpass and framebuffer to actually reuse part of the data/ attachments called, with flags as DON'T_CARE, simplifying partially on how we actually call attachments including their barriers and conditions (occlusion, etc), the DON'T_CARE it's specifically useful to not only prevent calling new loads (which is a flush and heavier on tiler devices) and not only reusing the actual data store, which works on the future time, this saves memory bandwidth and gives space to actually avoid the constant pressure on SYSMEM/GMEM shader resolver path.
This maintenance also improved the current removal features logic on QCOM drivers, closing gaps between implementations on descriptors (VK_EXT_indexing_descriptor), adjusting the whole WMEL to avoid being so stricter if certain capabilities are missing to actually use this feature, leading to test and play more on how QCOM drivers are actually behaving; meanwhile the main objective is to open path for a robust and bigger implementation in the future, the changes made here also contains small bug fixes on SPIR-V logic, adding missing cases to resolve shaders (FP64 -> FP16), adding more robustness on how narrow features are actually being used and how to wired them whenever they're not available, meanwhile there are still some issues in regards on how Tegra vs Adreno can preserve unorms at FP32 and FP16, leaving better understanding on base for what VK_EXT_shader_float_controls is actually doing most of the times (flushes NaN's and Denorms equally).

This simplifies the GPU accuracy setting by removing the intermediate Balanced mode and setting High as the default on desktop platforms.
It introduces a dedicated setting for GPU fence behavior, allowing the synchronization policy to be configured independently of GPU accuracy.
The Vulkan buffer cache now tracks GPU recording timeline ticks and waits only when necessary, reducing unnecessary synchronization while maintaining correctness for hard-to-trace graphical bugs.
GPU buffer readback has also been refined to synchronize only the affected upload regions when needed, and default DMA behavior has been updated to align with the new GPU accuracy model.
### TL;DR
The fix for particles freezing and unfreezing in mid-air in `Super Mario Odyssey` has been improved, resulting in less of a performance hit.
This game requires the new `Enable GPU Buffer Readback` option to be enabled to fix this issue.
The vertex explosions that occurred in `Super Mario Bros. Wonder`, especially in World 4, have been completely eliminated. You can now enjoy a smooth experience without graphical glitches exploding across the screen.
This game requires the new `GPU Fence Behavior` option to be set to `Strict` to fully fix this issue.
The flickering issue inside certain Shrines in `The Legend of Zelda: Tears of the Kingdom` has also been fixed.
For now, this game requires the new `GPU Fence Behavior` option to be set to `Accurate` to fully fix this issue.
These options are intended to fix graphical bugs in games that require better synchronization behavior between CPU and GPU, so other games may be affected as well.

This is the first step into the conversion on full GPU video decoding for Android; currently due to the VIC structure, I couldn't set it on surface mode to prevent the latency when sending video decoded (which is processed by GPU now), because currently we convert YUV420 into the Nvidia's format each frame constantly on CPU, aside the requirements from other extensions to work + VIC rewrite, which is a work currently not planned to happen on this PR; the actual configuration for video decoding is ByteBuffer, using GPU to decode NVDEC data (all codecs supported, h264, vp8 and vp9) and send it to CPU for display purposes, which is more faster than relying purely on CPU for any drawing task, saving devices resources/ heating, the downside on this will be the slight latency when a new frame is displayed, which is gonna be a black frame for less than a second, nothing major to harm the experience rather than actually trying our best to take advantage on hardware accelerated.
Aside this, I also added a bunch of minor Vulkan fixes to grant drivers less thinkering when receiving spir-v instructions, meaning this has new bans for extensions on QCOM (following reported issues on other projects working around Adreno driver behavior), this more than providing performance aims to enhance the stability on the driver, performance it's gonna likely to be hit based on the UBO's (StorageBufferAccess) operations and SSBO (uniformStorageBufferAccess), there was an already existing path for the emulation which forces to wide them into 32bit packed operations. I also included some smaller changes/ bugs + VUID's fixes from earlier changes on my work.

Based on the register of the ASTC implementation from Ameerj (yuzu), currently our conversion from ASTC on Desktop tends to duplicates the unpacking of ASTC converted textures, leading to bad performance; since there are some graphical effects that actually access on the band of 32bits (RGAF32) than the common 16bits (RGAF16) from our ASTC path decoding method, which commonly uses ARGB8 (degradation -> LDR) transformation to reduce the memory cost per conversion; meanwhile it could actually provide initially better performance; the engine tended to get stalled when this writted stage effect got skipped; mostly because CPU tends to look for an unimplemented texture/ format query (from which doesn't exist on our MaxwellToVK); unlike what's commonly believed HDR was a format to write enviroment effects even before their appearance on video output (since Switch doesn't have HDR, only SDR on certain engines).
The test result on this PR showed games like Astral Chain and other heavy reliant on ASTC decoding improved their performance and stability by around 15%; meanwhile could it be tied to a hardware gain, it's clearly a gain for direct access on what's required on most games. This PR also contains few Vulkan bug fix I encountered along this implementation.

Following the philosophy on the previous Vulkan maintenance PR's, this one is reviewing the video_core to resolve VUID's related to the missing handling/ safechecks (UBO's case on missing StorageBufferAccess 8/16 bits on QCOM drivers, resulting on bad compute pipeline compiled), wiring topology representative to EDS2 configuration (following #4117), refactored the sampled image access via new memeber function for type "typeless" which adds a handling on the integer mistmatch (uint to sint, float to uint) + fixing bugs on current texture sampling (int) including the depth/stencil path resolve, maintenance to previous changes on query cache (resolving bugs from #3853), reduced the amount of binding BindVertexBufferEXT2 when a new tick/ frame is presented (with this being a reason for performance reduction on games where vertex polutes the stage, like BOTW/TOTK where grass is draw with vertex); implemented color border swizzle and color write enable for future improvements on EDS3, added initial implementation on Synchronization2 starting a path to ensure an access to VK 1.3 features safely and other smaller fixes along the road.

This minor change in src\video_core\renderer_vulkan\pipeline_helper.h allows renderdoc capture on mhr sunbreak.
Maybe it sanitizes some crashes on old vulkan GPUs.
Device log (nvidia kepler gpu vulkan 1.1.117):
[ 17.605262] Render.Vulkan <Info> video_core\vulkan_common\vulkan_device.cpp:1041:GetSuitability: Device doesn't support feature nullDescriptor
VUID-VkWriteDescriptorSet-descriptorType-02997
For sampled/combined/storage image descriptors, Khronos says imageView must be valid or VK_NULL_HANDLE
(https://docs.vulkan.org/refpages/latest/refpages/source/VkPhysicalDeviceRobustness2FeaturesKHR.html)
but then it says: if nullDescriptor is not enabled, imageView must not be VK_NULL_HANDLE.
(https://docs.vulkan.org/spec/latest/chapters/descriptorsets.html)
nullDescriptor is exactly the feature that allows descriptors to be written with null handles.
The fix relies on conditionally replacing the null sampled view with Eden’s dummy null-image-view object (ImageView constructor checks HasNullDescriptor which checks features.robustness2.nullDescriptor. cheap checks, and only for null handles, so no notable cost).

FIXES A REGRESSION FROM 4012.
TryFindSize's Mesa fallback matched the unconditional @PT EXIT (0xE30000000007000F) that nv50_ir emits at program end.
That exact word is also emitted by NVN mid-program for unconditional early-outs, so on retail titles (e.g. Super Mario 3D World) the scan truncated at the first early EXIT and dropped the rest of the shader, making textures vanish.
Mesa's terminal EXIT and NVN's mid-program EXIT are bit-identical, so no mask can separate them. Gate the heuristic on !is_proprietary_driver:
NVN binaries (bindless cbuf slot 2) keep self-branch-only sizing, while nouveau/Mesa homebrew (single terminal EXIT, no self-branch trailer) still uses the EXIT terminator. nv50_ir emits exactly one EXIT (early returns lower to BRA-to-exit, discard to DISCARD), so a single terminal match is correct for that path.

EDS3 states were dynamic just because the driver supports them. But in EDS0-EDS2, we does not actually emit the EDS3 dynamic commands for them. So the pipeline builder skipped baking some fixed graphics state into the Vulkan pipeline, but the runtime also did not set that state dynamically. That leaves wrong Vulkan state during rendering causing rendering glitches in XC2.
