Simplified the call back for MaterialTypeSourceData::EnumeratePropertyGroups while also providing more data.
Made the Material Inspector join nested property group display names to be like "Layer 1 | Base Color", since the leaf property groups are shown as a flat list in the inspector.
Fixed CreateMaterialAssetFromSourceData to include the imported json files in the list of sourceDependencies. This triggers the Material Editor to hot-reload when one of these json files changes.
Updated a few places that were still assuming only one level of property group.
Updated EditorMaterialComponentInspector to apply the per-property-group material functors, before it was still only applying the top-level onces.
Moved some accessor function implementations to the cpp files, per feedback on another already-merged PR.
Testing:
Made changes to MinimalMultilayerPbr (in AtomSampleViewer) to use nested property groups, and saw the correct behavior in the Material Editor's property inspector.
Used MaterialComponent's property inspector to edit a StandardPbr material instance. Confrimed that functors were correctly controlling property visibility by enabling and disabling things like emissive and clear coat.
Used MaterialComponent's property inspector to edit a MinimalMultilayerPbr material instance. Saw all the expected groups and properties show up. Confirmed that per-group functors were correctly controlling property visibility.
Used MaterialComponent's property inspector to export a material instance and confirmed the .material file included the expected properties.

This is needed to support deeply nested material property groups, it just makes the serialization code a lot simpler than trying to support nested groups in the .material file. It also makes the file more readable and easier to search all files for particular properties.
I also updated MaterialSourceData to hide the property values behind a clean API.

This wrapper used to be needed in order to bind the custom JsonMaterialPropertyValueSerializer back when property values were represented by AZStd::any. Now that property values have a custom MaterialPropertyValue type, the wrapper class is no longer needed.

Fixed the MaterialBuilder to report source dependencies on imported JSON files, so the material type will rebuild when you edit an imported file that contains shared property data.
Fixed a spot in LuaMaterialFunctorSourceData where it was only applying the old "prefix" feature and not the new name context.
Updated a couple built-in material functors to take advantage of the name context (they were using RuntimeContext::GetShaderResourceGroupLayout instead of the RuntimeContext::FindShaderInputConstantIndex wrapper utility function).
Fixed an issue with EnumeratePropertyGroups where it wasn't passing the right name context, so Material Editor wasn't able to load some material types.
Reordered the parameters in the MaterialTypeSourceData enumerate callback functions, I felt this order was more natural.

The main addition here is the MaterialNameContext class which represents the concept of a namespace for properties, shader options, and SRG fields. This concept was already somewhat supported in LuaMaterialFunctor through bespoke "prefix" fields, but I have generalized it be available for all material functors. Note that I have not yet updated the other material functor types to ensure they take advantage of this feature, that will be in another commit.

I removed support for property rename version updates in MaterialTypeSourceData (i.e. ApplyPropertyRenames) because MaterialSourceData serialization no longer loads material property definitions from the .materialtype file, per a recent change on the development branch. The unit tests were broken and it wasn't worth updating them since we don't need this functionality anymore. Material property renames and other version updates are now exclusively applied by the MaterialAsset class.

Here the class has been generalized for a list of group names and a final property name, rather than assuming a single group containing the property. This included removing the unused GetPropertyName and GetGroupName functions. All that's really need from this class is conversion to a full property ID string.
Testing:
New unit test.
Reprocessed all core material types and StandardPBR test materials used in Atom Sample Viewer's material screenshot test.

These changes have the added benefit of simplifying some of the serialization code. MaterialSourceDataSerializer is no longer needed, as its main purpose was to pass the MaterialTypeSourceData down to the MaterialPropertyValueSerializer.
Before, the JSON serialization system gave a lot of data flexibility because it did best-effort conversions, like allowing a float to be loaded as an int for example. But now the material serialization code doesn't know target data type, so it has to assume the data type based on what's in the .material file, and then the MaterialAsset will convert the data to the appropriate type later when Finalize() is called.

I found a mistake where MaterialAssetCreator needs to clear the raw data when configured to finalize the material asset.
Since MaterialSourceData no longer relies on the material type source file at all, I was able to change MaterialSourceDataTest to avoid saving the source data to disk.

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.

The main reason for this is to give consistent results between the AP and Material Editor, where a placholder texture can be used if a texture is missing. Otherwise, you could get a placeholder texture in Material Editor and stale data in the runtime; this inconsistency would be confusing.
As a consequence, it is possible for example that the user could mess up the name of a property in a .material file and not notice the problem because it is now a warning instead of an error. If warnings-as-errors is desirable, you can enable the new "/O3DE/Atom/RPI/MaterialBuilder/WarningsAsErrors" registry setting.

Made it a warning instead of an error when MaterialAssetCreator can't find a texture.
Updated the Material Editor's MaterialDocument class to not elevate warnings to errors.
Material Editor uses new features in TraceRecorder to show a message dialog when warnings are detected so the user is notified of the missing texture.
Next I will work on making MaterialAssetCreator put a "missing" texture in place of the requested one.
