To solve menu item roles from their text, we need to find
its depth in the menubar hierarchy. Unfortunately, there's
no trivial way to access that hierarchy from the QPA side,
so we need to come with an ad-hoc solution.
Previously, we were using a dynamic proprety to keep track
of the 'parent' object. However, as the life span of the
different objects has changed since 09acf326db,
we need a way to keep track of the parent's existence.
This is what we do in this patch by having both QCocoaMenu
and QCocoaMenuItem also inherit QCocoaMenuObject. This class'
sole role is to store the menu hierarchy's parent object and
wrap it in a QPointer.
