- The config section is the DDSPI ShaderFormat of the shader platform
- BindlessResources and BindlessSamplers can be set independently
- The cvars still exist and will take precedence over the config settings.
- Renamed RHIGetBindlessResourcesConfiguration/RHIGetBindlessSamplersConfiguration to have the word "Runtime" in them to reflect that they should only be used at runtime and not when deciding if it's enabled for a shader.

The problem with this change is that late-created shader types will not be in the shadertype list and as such will not be included in the shader map even if their ShouldCompilePermutation() would return true.

Convert shader type and parameter struct metadata from global variables to static locals to defer initialization. This allows us to create these types dynamically at startup, while keeping the rest of the infrastructure as is.

RHI header dependency cleanup
- Reducing other header dependencies from RHIDefinitions.h
- Moved a few functions to the new RHIStrings.h
- Uniform buffer layout initializer moved to its own file to reduce RHI dependency on MemoryLayout.

Serialize the payload size as part of the raytracing shader so it can be examined in the RHI layer.
Validate that the RTPSO is configured with the appropriate payload size.
Add macros to ensure the payloads have the expected size
Ensure that all raytracing pipelines explicitly bind a miss shader
Add a shared shader header to implement static asserts for those shader compilers that support them (like dxc).
Fix payload type on main deferred reflection raygen shader
Fix incorrect raygen shader included in the deferred RTPSO list for RTGI
Don't add builtin shaders to the RTPSO from the RHI layer as these are unlikely to ever match the required payload type
Add new method to register payload types so that plugins can more easily describe custom payloads they may be using (up to a maximum of 32 unique payload types since we use a bitmask to represent payload sets).

- FlushShaderFileCache() used to be called to force all shader types to update their list of referenced uniform buffers, but they are only updated if they were ever used to compile in the current session. This would impact *any* shader type that had been used instead of just being limited to changed shader types.
- Moved the uniform buffer reference updating into a new function: UpdateReferencedUniformBufferNames.
- UpdateReferencedUniformBufferNames should be called before all shader recompiles but after FlushShaderFileCache does reset itself. This function requires a list of outdated types so we can reduce the shader type updates to only the types that need it.

- Remove shader platform specific info from uniform buffers, we can generate code with macros that translates to what each platform needs.
- With the per-platform differences removed, uniform buffer declarations (read: generated text) can be created once per shader parameter type that needs them instead of once per shader type's shader parameter type usage.
- FShaderType and FVertexFactoryType now hold a TSet of used uniform buffer names instead of a TMap that held potentially duplicated FStrings of uniform buffer defintions.
- Lists of uniform buffers are *potentially* different per platform, so the annoying CachedUniformBufferPlatform variables need to stick around for now.
- GenerateReferencedUniformBuffers renamed to GenerateReferencedUniformBufferNames and now populates a TSet instead of a TMap.
- ShaderType::AddReferencedUniformBufferIncludes renamed to ShaderType::AddUniformBufferIncludesToEnvironment which calls the shared UE::ShaderParameters::AddUniformBufferIncludesToEnvironment.
- CreateUniformBufferShaderDeclaration moved to UE::ShaderParameters::CreateUniformBufferShaderDeclaration and now returns its FString.
- CacheUniformBufferIncludes was removed since it was only populated values from CreateUniformBufferShaderDeclaration.
- Deprecated FShaderCompilerInput::SourceFilePrefix since nothing has populated it in 9 years.
