[Vk] Improve Stencil Handling and Fix Read-After-Write Hazard (#235)
1. Improves stencil handling:
- Adds surface type detection to distinguish between color, depth, stencil, and depth-stencil formats
- Only enables stencil load/store operations for surfaces that actually contain stencil data
- Avoids unnecessary stencil operations for non-stencil formats (DONT_CARE)
2. Fixes read-after-write (RAW) synchronization hazards:
- Adds a subpass self-dependency (subpass 0 → subpass 0)
- Synchronizes color/depth writes with subsequent shader reads
- Uses VK_DEPENDENCY_BY_REGION_BIT for efficient synchronization
- Covers all possible relevant stages,
• src: Color output + Early/Late fragment tests
• dst: Fragment shader
• Access: Write → Read transitions
here is what hazard looks like [1147.550616] Render.Vulkan <Critical> video_core/vulkan_common/vulkan_debug_callback.cpp:DebugUtilCallback:55: Validation Error: [ SYNC-HAZARD-READ-AFTER-WRITE ] Object 0: handle = 0x7409630000000192, type = VK_OBJECT_TYPE_IMAGE_VIEW; | MessageID = 0xe4d96472 | vkCmdDrawIndexed: Hazard READ_AFTER_WRITE for VkImageView 0x7409630000000192[], in VkCommandBuffer 0xb400007cb003ea70[], and VkPipeline 0x44d3470000000213[], VkDescriptorSet 0x0[], type: VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, imageLayout: VK_IMAGE_LAYOUT_GENERAL, binding #2, index 0.
