    libstdc++: Handle EPERM for filesystem access errors on MacOS [PR 99537]

    Contrary to what POSIX says, some directory operations on MacOS can fail
    with EPERM instead of EACCES, so we need to handle both.

    libstdc++-v3/ChangeLog:

            PR libstdc++/99533
            * src/c++17/fs_dir.cc (recursive_directory_iterator): Use new
            helper function to check for permission denied errors.
            * src/filesystem/dir.cc (recursive_directory_iterator):
            Likewise.
            * src/filesystem/dir-common.h (is_permission_denied_error): New
            helper function.
