Deduplicate legacy _ctor and _new Python bindings (#73822)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73822
I guess hypothetically the logic duplication here is a faux
amis because we could say that the constructor and new method
should evolve APIs independently... but nah, it's not worth it.
There is only very slight differences between the two functions:
different error messages, and the new method does extra checks
to make sure the requested types are consistent with the base
Tensor. But I need to refactor this code and I really don't want
to do the refactor twice. So dedupe first.
