CPP12 — need mapping for get_orb and get_component on CORBA::Object

The Core issue that adds get_orb to CORBA::Object has passed. It would
be good if you were to initiate an issue in the C++ RTF to make the
necessary changes in the C++ pseudo-object mapping section for Object to
incorporate this new operation. While you are at it you might also wish
to throw in the get_component operation, which was added by the
Components specification, and is yet to get into the C++ mapping chapter
(I think).

These might be way easier tor esolve than some of the weightier issues
that you have been struggling with, since these have very
straightforward and non-controversial resolutions

same as proposed resolution for issue #4871
