The PDB name is either retrieved from the PDB blob part of DXC's output, or is generated using the shader hash that DXC reports even when no PDB is requested. We don't export PDBs because it would result in duplicate data as we use embedded PDBs.

- ELanguage and Input flags were being used inconsistently to determine defines and shader profiles to use.
- ED3DShaderModel now communicates the exact shader model to use to the FXC and DXC backends.
- Moved all D3D custom definitions to ModifyShaderCompilerInput
- D3D definitions have been fixed to be based on specific needs of input flags. ie- "PLATFORM_MAX_SAMPLERS" doesn't imply that wave operations are wanted/supported.

- Removing the need for COMPILER_DEFINE on GetResourceFromHeap and GetSamplerFromHeap
- FShaderParameterParser constructor now requires a FPlatformConfiguration object that each shader format can configure.
- FPlatformConfiguration::GenerateBindlessAccess allows each platform to generate the code for accessing a bindless resource or sampler.
- Added EShaderParameterParserConfigurationFlags to specify support for stable constant buffers and bindless.
- Moved EBindlessParameterMode into EShaderParameterParserConfigurationFlags::BindlessUsesArrays
- While moving things around, I was able to convert some TCHAR* uses to FStringView

- Moving more uses of ShaderParameterParse from Preprocessing to Compile step.
- Adding a "DidModifyShader" flag to ShaderParameterParser to determine if Output.ModifiedShaderSource needs to be updated.

- When generating Uniform Buffer HLSL code, a 'static const struct {} Name' was created which has been causing compiler issues off and on for years.
- When RemoveUniformBuffersFromSource removed said struct, it parsed the struct's structure to figure out how to translate UniformBuffer.Member into UniformBuffer_Member in code that accessed Uniform Buffers.
- Now, instead of a struct, a "UniformBuffer <Name>" declaration is created and filled with mappings from "UniformBuffer.Member" into the correct code.
- This allows ConstantBuffer objects to be used differently from cbuffer where the former generates "UniformBuffer.Member" and the latter generates "UniformBuffer_Member"
- This also allows resources to always be translated to "UniformBuffer_Member"
- Shader define 'PLATFORM_SUPPORTS_UB_STRUCT' is now 'PLATFORM_SUPPORTS_CONSTANTBUFFER_OBJECT' and will be set on shader formats that support ConstantBuffer<> objects.
- Removed lots of unused code from BindlessResources.ush
