Remove several overrides of Views::GetClassName

Metadata macros already create a GetClassName function. For classes
that already implement metadata GetClassName is not needed especially
since most of the time the returned classname is the same as the macro
version. Remove these overrides. For classes that do not have
metadata implemented, implement metadata and then remove overrides.

No class name changes for the files in this CL
