libstdc++: Disable std::formatter specializations (LWG 3944)
This was just approved in Tokyo as a DR for C++23. It doesn't affect us
yet, because we don't implement the __cpp_lib_format_ranges features. We
can add the disabled specializations and add a testcase now though.
libstdc++-v3/ChangeLog:
* include/std/format (formatter): Disable specializations that
would allow sequences of narrow characters to be formatted as
wchar_t without conversion, as per LWG 3944.
* testsuite/std/format/formatter/lwg3944.cc: New test.
