Make it possible to check the accepted state of touch events in tests

QTouchEventSequence simulates a QPA touch event, potentially containing
multiple points. (Despite the name, it only calls qt_handleTouchEvent()
once, so it cannot really send a sequence of events; however, one event
can contain multiple touchpoints.) Delivery is synchronous, and we keep
return values through the QWindowSystemInterface::handleTouchEvent()
template functions; so the remaining step is to return a bool from
qt_handleTouchEvent(), so that we can return a bool from commit().
This allows tests to see the same perspective as a platform plugin can:
check whether the event was accepted or not, after delivery is complete.
Some tests in Qt Quick need to start doing that, to enforce correct
behavior in QQuickDeliveryAgent.

[ChangeLog][QtTestLib] QTouchEventSequence::commit() now returns a bool
so that tests can check whether the event was accepted during delivery.
