edje: fix edje RTL description in case of custom state of a part

This patch is from opensource (59681c331139e4d5424e77ff1614dc47fa8ddd8e, f5c4cd2f7f51f739f5f69eb4c857ccbfd8d51b0a)

    Summary:
    In case of RTL, the "custom" state properties does not apply. It happened because we don't copy the latest src to
    dst in set_state(PART:.., "custom", 0.0); in case of dst is already populated.
    We should copy the updated src to dst whenever we set the new custom description.
