- the xcode and cmake projects were updated to use cpp17
- a variable was renamed in opt_copy_propagation_elements to fix a compilation error on linux
- remove the register keyword from the autogenerated lexer code using a define
- added and modified scripts to fix the compilation process

- 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

OpenGL ES and Metal use framebuffer fetch.
Vulkan uses dual source blending.
For Vulkan and OpenGL ES there is a fallback shader permutation for drivers that don't support this. The fallback is the same as the existing solution that uses regular blending (i.e. looks different).
Others uses dual source blending and we force use of DXC for those shaders.

- Changing all shader versions to Guid.
- Fixing shader version guids in shaders to not be in comments.
- Adding a shader version to RayTracingCommon.ush.

- 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

- enable minifier deadstripping for OpenGL shader format; bytecode is a 100% match with this change on multiple tested projects so it seems safe to enable
- deprecate FOpenGLFrontend; nothing in available code appears to inherit from it anymore so the API appears unnecessary. this makes the OpenGL shader format more similar to others (which do not expose compilation functions as API)

- mostly just replacing them AllowWindowsPlatformTypes.h / HideWindowsPlatformTypes.h
- some other files had both Pre/PostWindowsApi.h and Allow/HideWindowsPlatformTypes.h, so just removed
- some occasional include order changes.

- Remove the condition causing SCW to automatically exit after a single job if HLSLcc was used. This doesn't appear to be beneficial; HLSLcc uses a lot of memory but does not appear to leak it, so we're wasting time spinning up new processes unnecessarily here. This allows us to deprecated the associated field in the compiler output and function in IShaderFormat.
- Strip out compiler invocations stats; this was not accurate in some cases and it was decided after discussion that at this point the effort to fix the problems was not worth the utility we get from it.
