Implement theTypeDescriptionManager directly on top of unoidl::Manager and
unoidl::Provider in cppuhelper instead of on top of css.reflection UNO
interfaces in stoc. Adapt desktop/source/deployment/ accordingly.
There is no longer a com.sun.star.reflection.TypeDescriptionManager service
implementation now, only a com.sun.star.reflection.theTypeDescriptionManager
singleton one, which appears to not cause problems in practice.
