    libstdc++: Move [[nodiscard]] attributes again [PR101782]

    Where I moved these nodiscard attributes to made them apply to the
    function type, not to the function. This meant they no longer generated
    the desired -Wunused-result warnings, and were ill-formed with Clang
    (but only a pedwarn with GCC).

    Clang also detected ill-formed attributes in <queue> which this fixes.

            (ranges::rbegin, ranges::rend, ranges::size, ranges::ssize)
            (ranges::empty, ranges::data): Move attribute after the
            declarator-id instead of at the end of the declarator.
            * include/bits/stl_iterator.h (__gnu_cxx::__normal_iterator):
            Move attributes back to the start of the function declarator,
            but move the requires-clause to the end.
            (common_iterator): Move attribute after the declarator-id.
            * include/bits/stl_queue.h (queue): Remove ill-formed attributes
            from friend declaration that are not definitions.
