Repurpose XcodeVersionInShaderVersion into UseFullMetalVersionInShaderVersion, setting this to true will force shaders to rebuild for each new Xcode version (reverting to previous behaviour)

The shader code output contains a little bit of plaintext such as I/O identifiers and the shader name, which was generated for the DXC backend in a way that prevents caching.
This unifies the shader name in the output code and improves the cache hit ratio for a Lyra cook from 0% to roughly 50% cache hits (for certain platforms).

* Significantly reduces the size of shader debug data and improves shader compilation time (reducing parsing cost in the native shader compiler)

- Making ConstantBufferType a constructor only argument. This removes the duplicated logic of calling ShouldUseStableConstantBuffer.
- Moving ShouldUseStableConstantBuffer to ShaderCompilerCommon.
- Made UE::ShaderCompilerCommon::ParseParameterType array arguments const

- Instrument how long shader preprocessing takes for each shader compilation job.
- Keep a running total in our shader stats per shader type.
- Add logging to track total thread preprocessing time for all shaders.
- Fixup local variable names to match the output log names.

- Refactoring FShaderParameterParser to use more string views since we can rely on OriginalParsedShader not changing.
- Split FShaderParameterParser::ParseAndMoveShaderParametersToRootConstantBuffer into smaller functions
- Moving FShaderParametersMetadata::IterateShaderParameterMembers into the only module it's used in, ShaderParameterParser.cpp
- Adding CFLAG_BindlessResources which will be set when ENABLE_BINDLESS_RESOURCES is set
- Adding CFLAG_BindlessSamplers which will be set when ENABLE_BINDLESS_SAMPLERS is set
- Adding resource/sampler detection and conversion to bindless in FShaderParameterParser
