Still had the issues with libusb, but that should get solved with the other PRs anyways

Adds native support for QCOM cubic filter weights, and for devices whom do not support said weights, just implement them in shaders
TODO: ZTC filter is wrong!?

This implements the use of VK_FILTER_CUBIC_EXT as a replacement for the software-based bicubic window adapting filter, used primarily for texture sampling in upscaled or downscaled surfaces such as UI, transparency effects, and screen-space elements in Unreal Engine 4 titles.
The Vulkan cubic filter is now conditionally enabled if the following are satisfied:
The device supports VK_EXT_filter_cubic
The format used supports VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_EXT
This change improves visual quality while reducing GPU workload by offloading cubic filtering to the driver instead of running custom sampling code in shaders. On supported hardware (e.g. desktop GPUs or high-end Adreno/AMD devices), it results in smoother transitions, improved transparency sampling, and better fidelity with lower shader complexity.
Fallback to the original software bicubic logic remains in place for devices lacking the extension or format capability.
Tested on several UE4 titles and confirmed to preserve or enhance visual output, especially in alpha-blended and UI-heavy scenes.

Refactors and improves the texture format conversion system in the Vulkan
renderer:
- Adds proper sRGB to linear conversion for depth formats
- Improves shader accuracy for ABGR8 SRGB to D24S8 conversion
- Adds gamma correction and proper depth range clamping
- Moves GetSupportedFormat implementation to header
- Cleans up format conversion switch statement
- Removes redundant format conversion paths
The changes improve accuracy when converting between color and depth
formats, particularly for sRGB sources. The shader improvements ensure
proper gamma correction and depth range handling.
Technical changes:
- Improves sRGB to linear conversion in fragment shader
- Adds proper depth value clamping
- Consolidates format conversion logic
- Removes duplicate GetSupportedFormat implementation
Adds several new shader-based format conversion pipelines to support additional
texture formats and operations:
- RGBA8 to BGRA8 conversion
- YUV420/RGB conversions
- BC7 to RGBA8 decompression
- ASTC HDR to RGBA16F decompression
- RGBA16F to RGBA8 conversion
- Temporal dithering
- Dynamic resolution scaling
Updates the texture cache runtime to handle these new conversion paths and adds
helper functions to check format compatibility for dithering and scaling
operations.
The changes include:
- New shader files and CMake entries
- Additional conversion pipeline setup in BlitImageHelper
- Extended format conversion logic in TextureCacheRuntime
- New format compatibility check helpers
Implements conversion from sRGB color formats to D24S8 depth-stencil format
in the Vulkan renderer. This change includes:
- New fragment shader convert_abgr8_srgb_to_d24s8.frag that handles proper
sRGB to linear conversion before depth calculation
- Added shader to CMake build system
- Extended BlitImageHelper with new conversion pipeline and methods
- Updated texture cache to handle sRGB to D24S8 format conversion paths
The conversion properly handles sRGB color space by first converting to
linear space before calculating luminance values for the depth component,
while preserving alpha channel data for the stencil component.
Removes unnecessary d32f to bgra shader and blit functions,
update vk_texture_cache to use abgr shader for d32f to BGRA formats
updates abgr to d32f shader to comply with hardware tests
