COMP: Fix MSVC /permissive- error C2516: ... is not a legal base class

Works around compile errors that appeared using Visual C++ compiler flag `/permissive-` ("Conformance mode"), using either VS2019 or VS2022, saying: > error C2516: 'ConstIterator': is not a legal base class > error C2516: 'GlobalDataStruct': is not a legal base class Originally reported by Astha, March 14, 2022, and further discussed at "ITK build Error in itk::ShapedNeighborhoodIterator", https://discourse.itk.org/t/itk-build-error-in-itk-shapedneighborhooditerator/4861
