STYLE: Add itkVirtualGetNameOfClassMacro + itkOverrideGetNameOfClassMacro

Added two new macro's, intended to replace the old 'itkTypeMacro' and
'itkTypeMacroNoParent'.

The main aim is to be clearer about what those macro's do: add a virtual
'GetNameOfClass()' member function and override it. Unlike 'itkTypeMacro',
'itkOverrideGetNameOfClassMacro' does not have a 'superclass' parameter, as it
was not used anyway.

Note that originally 'itkTypeMacro' did not use its 'superclass' parameter
either, looking at commit 699b66cb04d410e555656828e8892107add38ccb, Will
