Implemented support for wave operation intrinsics (Shader Model 6.0) as an extension of SP_PCD3D_SM5, available when running on compatible hardware and D3D12.
...
Wave intrinsics can be enabled for a shader by providing CFLAG_WaveOperations to the compiler flags in ModifyCompilationEnvironment().
Run-time availability must be queried by checking GRHISupportsWaveOperations before trying to use a shader that uses wave intrinsics.
Removed all RHI_RAYTRACING define checks from D3DShaderCompiler.cpp.

EShaderFrequency no longer depends on whether RHI_RAYTRACING is enabled. All frequencies are always defined. Some of the usage of SF_NumFrequencies is replaced with SF_NumStandardFrequencies to avoid memory and run-time overhead.

Remove tessellation function constant as we can use linear-textures to achieve the same result which means we no longer need separate variants of the shader. DrawIndexedPrimitiveUP can no longer draw a tessellated mesh - but that was never advisable anyway.

Remove all support for Metal prior to Metal 1.2 on iOS/tvOS and Metal 2.0 on macOS. This permits some fairly radical simplifications and removal of a number of workarounds.
...
- All Buffer<>/RWBuffer<> objects are now bound as texture2d or texture_buffer, unless they are 3-component, in which case they are bound as raw T* buffer pointers.
- 3-component Buffer/RWBuffer objects should now work - Metal needed to use packed_* types internally as normal 3-component types in Metal are the same size as 4-component types which is different to HLSL. This is untested as we have no such example.
- Texture Gather/GatherCompare operations have been fixed and should now work.
- Remove all the TypedBufferFormat function-constant specialisation infrastructure and metadata as it is no longer necessary.
- Remove all the raw-conversion for 1, 2 and 4 component vector types as it is no longer required.
- Fixed input qualifiers (centroid, linear, etc.) for Fragment shader inputs - they should now work.
- Remove a bunch of Metal specific shader changes due to buffer type casting and swizzling that will now just work.
- Use the BGRA vertex format for FColor on Metal when available (everywhere but iOS/tvOS 10 using Metal 1.2).
- Simplify ShouldCompilePermutation & similar functions now that we have fewer versions to support.
