* Create helper function for getting threads per
group from a compute shader
Added GetComputeShaderNumThreads() functions to RPIUtils.
By default the function returns 1, 1, 1 in case of errors.
Updated existing code that was looking for 'numthreads' attribute data
with the new GetComputeShaderNumThreads() API.

This was done while working on "ATOM-15728 Shader Hot Reload Fails in Debug Build", but it turned out these changes did not actually fix the issue (or any other known hot-reload issue). Still, these improvements are appropriate as they correct logical oversights.
ShaderVariant was not listening to asset reloads. It needs to know when the ShaderVariantAsset reload happens so it can reinitialize it's members as well as propagate reinitialization messages. I added a member for the ShaderAsset as the class needs this to reinitialize itself. So now the class listens for reloads of both the ShaderVariantAsset and the ShaderAsset.
Shader was not listening for ShaderAsset reinitialization events.
Updated the API for ShaderReloadNotificationBus's OnShaderVariantReinitialized to include the ShaderVariant which is the most relevant information (the other information wasn't really being used anyway).
* [ATOM-15472] Shader Build Pipeline: Remove Deprecated Files And Functions That
Predate The Shader Supervariants
These are the essential impactful changes as a result of deprecating the
ShaderResourceGroupAsset.
* Addressed feedback by @moudgils. Better comments in header files.
* More updates related with deprecation of ShaderResourceGroupAsset
* Deleted the temporary version 2 classes.
* Updated version of the shader asset builders.
* Updated version of all the shader related classes impacted
by the Supervariant concept and deprecation of ShaderResourceGroupAsset
* Changes to *.pass and DGI, Reflections and RayTracing.
* changes to material related assets
* changes to core lights
* Changes to auxgeom/dynamic draw.
* changes to decals, lyshine, imguipass
* changes to RPI Pass classes
* Shader for SceneSrg, ViewSrg and ForwardPass Srgs.
* changes to mesh, skinned mesh, Morphtarget.
* Fixes to RayTracingPass.cpp & now allow empty srg in shaders.
* Updated Atom_RPI.Tests
* Simplified InstanceDatabase by removing AddHandler
------------------------------------------------------------------------------------
* Updated DiffuseGI precompiled shaders.
Added RayTracingSceneSrg and RayTracingMaterialSrg shader asset.
Updated ShaderAssetCreator::Clone to handle the supervariant when processing root variants.
Co-authored-by: Doug McDiarmid <dmcdiar@amazon.com>
------------------------------------------------------------------------------------
* Changed semantics for some PassSrg to SRG_PerPass_WithFallback.
AuxGeom/FixedShapeProcessor.cpp requires SRG_PerDraw on ObjectSrg.
Removed names of SceneSrg and ViewSrg from RPISystemDescriptor.cpp
* Moved ShaderLib/Atom/Features/DummyEntryFunctions.azsli
To Gems/Atom/RPI/Assets/ShaderLib/Atom/RPI/DummyEntryFunctions.azsli
Removed redundant checking for finalization in
ShaderResourceGroupLayout.cpp
* Fixed race condition bug for Shader::FindOrCreate.
InstanceDatabase<>::CreateInstance() needs to be atomic
for instance creation and initialization.
Added optional InstanceHandler::CreateFunctionWithParams to accomodate
to the needs of Instances that need more than an asset reference
to be able to be created an initialzed.
Removed ShaderResourceGroup::FindOrCreate() only ::Create is available
now.
* Renamed scene_and_view_srgs.* as SceneAndViewSrgs.*
Changed GetAzslFileOfOrigin for GetUniqueId
* Fixed unit tests.
* Reverted the serialization name of m_uniqueId back to
"m_azslFileOfOrigin" so precompiled shaders don't fail
in layout comparison.
* Fixed AtomCore.Tests
Removed non-applicable test. InstanceDatabase.AddHandler() is not
available anymore.
* The Null rhi is re-enabled for shader compilation.

Previously, the SkinnedMeshFeatureProcessor assumed there would only be one skinning pass. However, that's not always the case. When rendering with track view, the feature processor was getting a pass that only updated once every three frames, which could lead to a condition where a skinned mesh was released, but the pass never submitted and cleared the previously added dispatch items, and one or two frames later it would go to submit after the skinned mesh and all of its resources had already been released.
-Modified the skinning and morph target compute passes to pull dispatch items from the feature processor instead of the feature processor pushing them to the passes.
-If more than one skinning (or morph target) pass is active in the frame, whichever one is first will submit all the dispatch items, and clear the feature processor's dispatch items before the next one tries to submit anything
-Moved the logic for caching shader options from the SkinnedMeshComputePass to the SkinnedMeshFeatureProcessor, since there may be more than one pass but only one feature processor per scene
