moc: fix support for generating meta objects for nested private classes

introduced a new QT_OBJECT_GADGET_COMMON macro, causing my
`--enable-qt6` clang plugin build with current qtbase git dev
(as of commit 957e2be00a5c45223a5ef842a5f9f2f7b7be882b)
to fail as follows for classes using the Q_OBJECT macro:

Extend the plugin to also take the new macro into account in
addition to Q_OBJECT.
