[Vulkan][TextureCache] Always use identity-swizzled views for storage images ( #321 )
...
Validation flagged writes to a VK_DESCRIPTOR_TYPE_STORAGE_IMAGE descriptor because the bound VkImageView had a non-identity component mapping and hence the vuid-00336 error, this fixes the said error.
------
This commit helps to fix some graphical issues on games like Trident's Tale, where game didn't render anything than just plain terrain, helps to stabilize Nier Automata graphical issues, meanwhile the most annoying glitches are gone, there's still remain other issues.

[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
