Auto merge of #56842 - scottmcm:vecdeque-rotate, r=alexcrichton
Add unstable VecDeque::rotate_{left|right}
Like the ones on slices, but more efficient because vecdeque is a circular buffer.
Issue that proposed this: https://github.com/rust-lang/rust/issues/56686
~~:bomb: Please someone look very carefully at the `unsafe` in this! The `wrap_copy` seems to be exactly what this method needs, and the `len` passed to it is never more than half the length of the deque, but I haven't managed to prove to myself that it's correct :bomb:~~ I think I proved that this code meets the requirement of the unsafe code it's calling; please double-check, of course.
