I made MaterialAsset::Finalize private so I could add some parameters specifically for MaterialAssetCreator to use. Now MaterialAssetCreator::Begin has an option to finalize the material or not.
Moved MaterialAssetCreatorCommon::ValidateDataType to MaterialPropertyDescriptor as "ValidateMaterialPropertyDataType" so that MaterialAsset::Finalize could use it too

Before, the material builder was loading the MaterialTypeAsset and doing some processing with it, but was avoiding declaring job dependencies that would cause reprocessing lots of assets when a shader or .materialtype file changes. Reading the asset data isn't safe when not declaring a job dependency (or when declaring a weak job dependency like OrderOnce which is the case here). This caused to several known bugs.
The main change here is it no longer loads the MaterialTypeAsset at all; all other changes flow from there.
The biggest changes (when deferred material processing is enabled) are ...
1) MaterialSourceData no longer loads MaterialTypeAsset. All it really needs is to determine whether a string is an image file reference or an enum value, which is easy to do by just looking for the "." for the extension.
2) MaterialAssetCreator no longer produces a finalized material asset. It no longer uses MaterialAssetCreatorCommon because that only produces a non-finalized MaterialAsset, which has very different needs for the SetPropertyValue function. (We could consider merging MaterialAssetCreatorCommon into MaterialTypeAssetCreator since that's the only subclass at this point). And it doesn't do any validation against the properties layout since that can be done at runtime.
3) Moved processing of enum property values from MaterialSourceData to MaterialAsset::Finalize (this was the only thing being done in the builder that actually needed to read the material type asset data).
Also...
- Updated the MaterialAsset class mostly to clarify and formalize the two different modes it can be in: whether it is finalized or not.
- Merged the separate "IncludeMaterialPropertyNames" registry settings from MaterialConverterSystemComponent and MaterialBuilder into one "FinalizeMaterialAssets" setting used for both.
- Removed MaterialSourceData::ApplyVersionUpdates. Now the flow of data is the same regardless of whether the materials are finalized by the AP or at runtime. Version updates are always applied on the MaterialAsset.
- Added a validation check to MaterialTypeAssetCreator ensuring that once a property is renamed, the old name can never be used again for a new property. This assumption was already made previously, but not formalized, in that Material::FindPropertyIndex does not expect every caller to provide a version number for the material property name, also the material asset's list of raw property names was never versioned. The only way for this to be a safe assumption is to prevent reuse of old names.

I actually tried this approach before and it didn't seem to work the way we needed, but I realized that's because PropertyAssetCtrl wasn't handling missing assets properly. I fixed a few issues there including showing the error button when the asset can't be found, and fixing a broken reference to the error icon file.

Material Editor also warns the user when saving a material that is populated with fallback image references.
Factored out the path strings for the default images to ImateSystemInterface.h.

This required the use of custom serializers, because the JSON serialization system does not have any means of supporting field name aliases through SerializeContext.
Testing: RPI unit test pass and AtomSampleViewer material screenshot test script passes.
