    libstdc++: Use _wstat64 for Windows [PR 95749]

    In order to handle large files on Windows we need to use stat API with
    64-bit st_size member.

    libstdc++-v3/ChangeLog:

            PR libstdc++/95749
            * src/filesystem/ops-common.h [_GLIBCXX_FILESYSTEM_IS_WINDOWS]
            (stat_type): Change to __stat64.
            (stat): Use _wstat64.
