child event filter: Loosen check to only consider QWidget

Follow-up to a46e9f2036595e8d04cae68a719e5182718861bf to work correctly with
older Qt versions (< 6.4), where this is not a QQuickWidget apparently.

This also means we can simplify the workaround, as we are guaranteed to be on Qt
6.4+ anyways.

See #7820, #7831
