ENH: Check thisClass argument of GetNameOfClass macro calls

Asserted in both `itkVirtualGetNameOfClassMacro` and
`itkOverrideGetNameOfClassMacro` that `thisClass` is indeed the name of the
class that contains the macro call.

The assert helped finding three classes whose `GetNameOfClass()` member function
returned the wrong name.
