QMenu: guard for destruction when emitting action signals
If a slot connected to a QMenu-action destroys the QMenu, then
we must not touch data members in subsequent code, and instead return
immediately.
We cannot use QBoolBlocker here, as that would reset the data
member of QMenuPrivate even when trying to return early.
Fixes: QTBUG-106718
