Introduce QEvent::isSinglePointEvent()
This makes high-level event dispatching easier: for example we often
need to cast an event to access getters like button() and buttons().
We can so far assume that any QPointerEvent that is not a QTouchEvent
is a QSinglePointEvent; but more explicit type-checking looks safer.
Implemented in a similar way as c7f727996909338c3689396160f3060480521846.
