Update wxMenu::UpdateUI() parameter comment and documentation

Browse Source 
The argument to this method should basically just never be used, so while we
still keep it for compatibility (because it doesn't cost anything to do it),
make it clear that it should never be specified in the new code and, also,
that this function is actually only used inside wxWidgets and shouldn't be
normally called from outside of the library at all.
