Make new_empty/new_ones/new_zeros/new_full respect subclass (#65169)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/65169
Previously these composite functions created a new tensor
using at::empty (or some other factory function) using TensorOptions
which doesn't preserve Python subclass. Making new_empty a
non-composite op and then routing everyone through it makes it
respect subclass. We could also make all of these non-composite
but this reduces the number of derivatives.yaml entries I have to
make and allows you to trace the fill calls.
