Fix generation of Leave events when using tablet devices
When both mouse and tablet events are handled by QWindowsPointerHandler, m_currentWindow variable is shared among the two event streams, therefore each stream should ensure it does equivalent operations, when changing it. Here we should subscribe to the Leave events, when we emit Enter event from the inside of the tablet events flow. Without whis subscription, the cursor may stuck in "resize" state when crossing the window's frame multiple times.
