QAccessibilityHints: override QObject::event()

Provides a life-line if we have to add an event handler. We cannot, in
general, add new overrides (e.g. mouseMoveEvent()) to a released class,
as the new overrides may not be called by existing compiled code. By
having at least event() already overridden, we are free to place new
code there.

Amends d8ac4cd8692e77c85ac8c6bcfa0a1556c7a72ee9.

Pick-to: 6.10
