af2088d117 Implement an FMA pass that converts separate MUL + ADD pairs into FMAs - needed by older Metal standards to avoid floating point operation reordering that affects precision.

3722379958 Implement support for SPIRV-Cross's separate Metal tessellation shaders - this means streaming out the vertex data using a render-pass in the prologue command-buffer, followed by generating a patch index buffer & running the Hull shader as a compute pass and then finally running the draw call. This is slower and uses more memory than the unified approach taken in hlslcc but it is conceptually simpler and much easier to deal with one the shader compiler side.

- VertexInterpolator material expressions work correctly when creating lightmass/proxy materials
- Lightmass/Proxy replace switches don't attempt to evaluate non-active branch; this fixes problem when non-active branch has compile errors in the current context, which causes compile to fail

ad85a11bbd Parse the HLSL to extract the Hull shader attributes that have no SPIRV equivalent so can't be parsed from the SPIRV. This is likely to be more fragile but there's no real alternative.

2e2a1a084f A bit more work hooking up the various buffer indices into the Metal shader metadata - still more to be done before it will actually work and pass through everything we need.

6b4c570371 DR - The issue is that GameThreadShaderMap and the RenderingThreadShaderMap can get out of sync. And one case of this is when DefaultMaterials are forced though the !bApplyCompletedShaderMapForRendering path because bSynchronousCompile is set. Although it is noted that "if !bApplyCompletedShaderMapForRendering, RenderingThreadShaderMap must be set elsewhere to match up with the new value of GameThreadShaderMap" the Result is actually a dangling reference of RenderingThreadShaderMap. Therefore I removed bApplyCompletedShaderMapForRendering and force the synchronization of the RenderingThreadShaderMap via the SetGameThreadShaderMap interface each and every time it is changed.

7b0d188be6 Metal vertex shaders in tessellation pipelines must capture their output into a buffer so that it can feed into the compute-based hull shader. This is different than the HLSLCC approach which combined the Vertex & Hull shader, which we can't easily do with DXC.
