Fix: [ATen] add more missing moves - part 2 (#89000)
Applies some more missing std::move found by static analysis. This should improve performance and reduce unnecessary copies. This PR only targets ATen for now.
And before you ask about the edits, std::move is optimal in a ternary operator as copy ellision cannot happen one. The best thing is probably rewriting it as an if else, but ultimately this should be performant enough.
