Deprecate vtkUniformGridAMR in favor of vtkAMRDataObject and impact other similarly named class
Since !12312 (merged), vtkUniformGridAMR is an empty shell. It should be deprecated in favor of vtkAMRDataObject, as well as all other vtkUniformGridAMR* classes.
However, vtkUniformGridAMR is not a leaf of the heritage tree, making that deprecation complex if even possible with the current deprecation system.
