[LWFXEF] Change EObjectBasedDiagramControllerBase to work on EObjects

The type checks and model change providers have been edited in order for the class to actually work with EObjects:

• The EObjectBasedDiagramControllerBase has been changed to require EObjects only (not IHierarchicElements).
• The HierarchicModelElementModelChangeProviderhas been changed to require EObjects only and has thus been renamed to EObjectModelChangeProvider.
