Add QSinglePointEvent::exclusivePointGrabber convenience property
Since a single-point event (such as a QMouseEvent) only carries one
point, it only has one grabber, so we can have a normal Q_PROPERTY.
It's named exclusivePointGrabber to avoid shadowing the
QPointerEvent::[set]exclusiveGrabber functions that take QEventPoint&.
