    libstdc++: Disable std::formatter::set_debug_format [PR112832]

    All set_debug_format member functions should be guarded by the
    __cpp_lib_formatting_ranges macro (which is not defined yet).

    libstdc++-v3/ChangeLog:

            PR libstdc++/112832
            * include/std/format (formatter::set_debug_format): Ensure this
            member is defined conditionally for all specializations.
            * testsuite/std/format/formatter/112832.cc: New test.
