[libcxx-commits] [libcxx] [libc++][test] Unblock cases for `ranges::sort` with proxy ranges (PR #188490)

[A. Jiang via libcxx-commits]

https://github.com/frederick-vs-ja created https://github.com/llvm/llvm-project/pull/188490

libc++ switched to use `iter_move`/`iter_swap` long time ago, so we should unblock these cases.
