Add name propagation for at::alias, add tensor.set_names (#23624)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/23624
tensor.set_names(names) is the out-of-place variant of
tensor.set_names_(names). This naming is probably confusing so I am
taking any and all suggestions.
Test Plan:
- run tests [namedtensor ci]
