    libstdc++: Fix error reporting in filesystem::copy [PR99290]

    The recursive calls to filesystem::copy should stop if any of them
    reports an error.

    libstdc++-v3/ChangeLog:

            PR libstdc++/99290
            * src/c++17/fs_ops.cc (fs::copy): Pass error_code to
            directory_iterator constructor, and check on each iteration.
            * src/filesystem/ops.cc (fs::copy): Likewise.
            * testsuite/27_io/filesystem/operations/copy.cc: Check for
            errors during recursion.
            * testsuite/experimental/filesystem/operations/copy.cc:
            Likewise.
