16a9141e - [PyTorch] Update expand_outplace API to match expand_inplace (#55245)

[PyTorch] Update expand_outplace API to match expand_inplace (#55245) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/55245 Like `expand_inplace`, `expand_outplace` now returns `MaybeOwned<Tensor>` in most cases. I wasn't confident around the ownership semantics of the `TensorList` -> `std::vector<Tensor>` case, so I left that one alone. ghstack-source-id: 126170052 Test Plan: Existing CI.
