[PyTorch] Fix const correctness for resize native functions (#55351)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/55351
We incorrectly used `Tensor&` to mean "the underlying
TensorImpl cannot be changed", as explained in
https://github.com/zdevito/ATen/issues/27#issuecomment-330717839 .
This diff gets us on the path to fixing this problem: we have an
incremental way to fix individual native functions so that we can
apply any handwritten fixes a few at a time. It gets the migration
started with the `resize` family of native functions.
