moc: add a test for Q_FLAG getter/setter on integers

Browse Source 
This is legacy behavior from Qt 3, before we had QFlags and before
QVariant could support user types. I cannot find any instance of a
getter returning an integer in current Qt or Qt Creator code. And note
this only compiles if the flags type with Q_FLAG - not Q_ENUM.

The content is wrapped as Qt 6.x only so it can be removed in Qt
7.0. The deprecation warning will come in a later commit, for 6.9.
