ATOM-15837 Remove Unused Shader System Related *2 Classes From Stabilization Branch.
Testing: ASV full test suite on dx12 and vulkan. Only saw known issues.
ATOM-15728 Shader Hot Reload Fails in Debug Build
The main change was to add OnAssetReady handlers to each of the asset classes. See comments in ShaderAsset::OnAssetReady for a detailed explanation. In short, OnAssetReloaded gets missed while assets are being reloaded at the same time on multiple threads, but OnAssetReady is always called whenever connecting to the AssetBus because of its AssetConnectionPolicy.
The above change required the addition of a new AssetInitBus to call the PostLoadInit() functions. Because OnAssetReady connects to buses that are not mutex-protected, they have to be connected on the main thread. AssetInitBus::PostLoadInit is called every frame in RPISystem::SimulationTick. All Atom's asset handlers that need to do post-load initialization must connect to the AssetInitBus, and the asset will disconnect itself after initialization is complete.
We also need the Shader class to handle OnShaderAssetReinitialized to properly handle the shader reload.
With these changes I can click back and forth between "Blending On" and "Blending Off" many times (like 20 times) without issue.
* [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.

------------------------------------------------------------------------------------
* 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.

* [ATOM-15276] Shader Build Pipeline: Add Shader Supervariant System.
Added ShaderAssetBuilder2 & ShaderVariantAssetBuilder2.
Added ShaderAsset2, ShaderVariantAsset2.
Eventually they will be the only builders. AzslBuilder &
SrgLayoutBuilder will be removed.
ShaderResourceGroupAsset will be removed. ShaderAssetBuilder &
ShaderVariantAssetBuilder will be replaced.
