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.

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.
