Grabs result types for texture color sampling & also scalar ID's for proper formatting
Should resolve 90-95% of the black artifacting found in MP4

feat(spirv): implement texture component type handling in SPIR-V backend eb04a096de

Update SPIR-V backend to use component-specific sampled types for
textures, ensuring correct type conversions for integer and depth/stencil
textures.

- Add ComponentScalarType helper function
- Update ImageType to accept component-specific sampled types
- Add TextureColorResultType and TextureSampleResultToFloat helpers
- Update all texture sampling functions to handle component types
- Add output_s32 for signed integer outputs
- Add Flat decorations for integer inputs in fragment shaders
- Add NonWritable decoration for read-only storage buffers

feat(shader): add SamplerComponentType enum and infrastructure 46de959188

Add SamplerComponentType enum to classify texture component types
(float, signed int, unsigned int, depth, stencil) and add
ReadTextureComponentType method to Environment interface.

- Add SamplerComponentType enum with constexpr helper functions
- Add component_type field to TextureDescriptor struct
- Add ReadTextureComponentType virtual method to Environment base class

feat(video-core): add texture component type caching and serialization 9fa9a8056f

Implement texture component type conversion and caching in shader
environments, with full serialization support for shader cache.

- Add ConvertSamplerComponentType using std::bitset for component tracking
- Implement ReadTextureComponentType for Graphics/Compute/File environments
- Add texture_component_types cache to all environment classes
- Update Serialize/Deserialize to include component types
- Cache component types alongside texture types for performance

feat(shader): integrate component type into texture pass optimization f95faaade5

Update texture descriptor comparison to include component_type, ensuring
textures with different component types are properly differentiated.

- Add ReadTextureComponentType helper function
- Include component_type in texture descriptor comparison
- Use component type when creating texture descriptors

feat(renderer): add BCn unswizzle compute shader 9b7e7b26aa

Add block_linear_unswizzle_3d_bcn.comp compute shader for improved
BCn format support. The shader uses GLSL 460 and handles block-space
coordinate conversion for BCn compressed textures.

- Add block_linear_unswizzle_3d_bcn.comp shader
- Update host shaders CMakeLists to include new shader
