Relax tp_new so that it is OK to call (#57544)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57544
Instead of removing tp_new from the superclass (which causes
super().__new__ to not work), I now still install tp_new on the
superclass, but verify that you are not trying to directly
construct _TensorBase.
