Add SPIRV OpCapability for 8/16bit use in storage (#8194)
Emits the appropriate OpCapability for 8- and 16-bit type usage:
- UniformAndStorageBuffer8BitAccess: for 16-bit types in
SpvStorageClassUniform and SpvStorageClassStorageBuffer
- UniformAndStorageBuffer16BitAccess: for 16-bit types in
SpvStorageClassUniform and SpvStorageClassStorageBuffer
- StoragePushConstant8: for 8-bit types in SpvStorageClassPushConstant
- StoragePushConstant16: for 16-bit types in SpvStorageClassPushConstant
- StorageInputOutput16: for 16-bit types in SpvStorageClassInput and
SpvStorageClassOutput
Generated with Claude Code, with revisions.
Fixes #7879.
