Implement SPV_EXT_fragment_invocation_density (SPV_NV_shading_rate) (#8037)
* Implement SPV_EXT_fragment_invocation_density
-Adds semantics SV_FragSize and SV_FragInvocationCount and implements them for SPIRV and GLSL using the appropriate target builtins from extensions.
-Adds test case checking for expected target builtins from these semantics.
-For future work, could implement SV_FragSize using pixel shader input SV_ShadingRate for HLSL, and SV_FragInvocationCount needs research.
Fixes #7974
