* This avoids GPU under-utilization in scenes where a very large number of individual occlusion queries is issued
* Possible r.SceneDepthHZBAsyncCompute values:
* 0: Don't use async compute (default)
* 1: Use async compute, start as soon as possible
* 2: Use async compute, start after ComputeLightGrid.CompactLinks pass

- 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 This function requires a list of outdated types so we can reduce the shader type updates to only the types that need it.

- Also, add flushing the pending deletes in the attempt to make sure any leftover RHI resources from the assets that used that library (which should be already queued for deletion at this point) are deleted before we remove the backing storage.

- Moved dispatch busy-wait out of the command-list recording task. Allows the render thread to help with jobs once it's done.
- Added workload to pass to help load balancing.

bGreyScaleFormat is only used by debug/editor shaders, game runtime uses SamplerType from MaterialExpressions
bGreyScaleFormat bool is needed because FTexture does not have access to CompressionSettings
behavior is observably different with Grayscale G16 and cases like TC_Alpha non-multiple-of-4

Removal of includes to reduce transitive includes in high traffic headers to reduce compile times
Highlights
* Skeleton and BonePose not leaked out of commonly used animation headers
* AudioComponent leaking out less
* Brush not leaking Level.h (Brush is included indirectly a lot)
* VertexStreamComponent moved to its own file so Components.h can include that instead of VertexFactory (which would leak out all of RHI and others)

FRDGEventScopeStack::EndExecute did not pass the value of bRDGEvents to the scope array, so we ended up trying to pop events that were never pushed when bRDGEvents was false.

- SetShaderParameters and ValidateShaderParameters now require the caller pass in the size of the parameter data. This will be useful when making SetShaderParameters run on the RHI thread.
- SetShaderParameters no longer requires a FShaderParametersMetadata argument since it was never used.

- 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.
