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.
Original CL Desc
-----------------------------------------------------------------
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.

- 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.

This technique is guarded with by a projected settings. It is currently only supported on PC Dx12. This is the initial step for fine grain/per-pixel sorting.

This should fully address UniformBufferLayout/UniformBuffer crashes that randomly happen during shader compiling in the Editor.
