    libstdc++: Fix experimental::filesystem::status on Windows [PR88881]

    Although the Filesystem TS isn't properly supported on Windows (unlike
    the C++17 Filesystem lib), most tests do pass. Two of the failures are
    due to PR 88881 which was only fixed for std::filesystem not the TS.
    This applies the fix to the TS implementation too.

    libstdc++-v3/ChangeLog:

            PR libstdc++/88881
            * src/filesystem/ops.cc (has_trailing_slash): New helper
            function.
            (fs::status): Strip trailing slashes.
            (fs::symlink_status): Likewise.
            *
testsuite/experimental/filesystem/operations/temp_directory_path.cc:
            Clean the environment before each test and use TMP instead of
            TMPDIR so the test passes on Windows.
