    libstdc++: ranges::rotate should use ranges::iter_move [PR121913]

    Using std::move(*it) is incorrect for iterators that use proxy refs, we
    should use ranges::iter_move(it) instead.

    libstdc++-v3/ChangeLog:

            PR libstdc++/121913
            * include/bits/ranges_algo.h (__rotate_fn::operator()): Use
            ranges::iter_move(it) instead of std::move(*it).
            * testsuite/25_algorithms/rotate/121913.cc: New test.
