[libc++][ranges] Addresses LWG3759

[Mordante]

Summary

LWG3759 ranges::rotate_copy should use std::move

This has been one in the initial version (D127211).

[ldionne]

Do we have a test for this?

[ldionne]

I just checked and we do. We have a test with cpp20_output_iterator, which is move-only.

Thanks for the review, it somehow dropped of my review list.
