a53408a758 feat(shader): implement texture component type handling in SPIR-V backend 
- Add ComponentScalarType helper function
- Update ImageType to use component-specific sampled types
- Add TextureColorResultType and TextureSampleResultToFloat helpers
- Update all texture sampling functions to handle component types correctly
- Add proper type conversions for integer and stencil textures
- Add Flat decorations for integer inputs in fragment shaders
- Add NonWritable decoration for read-only storage buffers

This ensures textures are sampled with the correct component types,
improving accuracy for integer and depth/stencil textures.

c71cd53d0d fix(shader): Fix integer texture format mismatch in SPIR-V 
- Add is_integer field to TextureDescriptor and TextureDefinition
- Use IsTexturePixelFormatInteger to detect integer textures
- Update ImageType to use U32[1] for integer textures, F32[1] for float
- Merge is_integer flag when combining texture descriptors

d8d54c5ccf shader_recompiler: Fix alpha-to-coverage fragment output interface 
The Vulkan spec requires fragment shaders to declare an output covering
Location 0, Component 3 (alpha) when alpha-to-coverage is enabled. This change:

- Tracks alpha_to_coverage_enabled through RuntimeInfo from pipeline state
- Forces declaration of frag_color[0] with full RGBA when enabled
- Initializes alpha to 1.0 in shader epilogue if not explicitly written
