feat(shader): add SamplerComponentType enum and infrastructure 00421f4ace

- Add SamplerComponentType enum to shader_info.h
- Add ReadTextureComponentType to Environment interface
- Add texture_component_types cache to shader environments
- Update texture descriptor to include component_type field

This is the foundation for proper texture component type handling.

feat(shader): implement texture component type handling in SPIR-V backend a53408a758

- 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.

feat(shader): integrate component type into texture pass optimization 65daba6179

- Update texture descriptor comparison to include component_type
- Add ReadTextureComponentType helper in texture_pass.cpp
- Use component type when creating texture descriptors

This ensures texture descriptors are properly differentiated by component type.
