[API CHANGE] Remove deprecated com.sun.star.uno.Union class

...which had never been useful for anything, as UNOIDL does not have a union
concept.  In light of coverity#1327215 "UwF: Unwritten field," seems cleaner to
just remove that class completely than to silence that somewhat bogus (as the
class is non-final, so derivations could actually set m_value) Coverity warning.
