Windows: Prevent spurious leave events.
When behind a mouse-event-transparent window, synthesized leave events
are emitted, because the transparent window is considered as the window
under the mouse, not the Qt window.
This change skips transparent windows when searching for the window
under the mouse.
Task-number: QTBUG-31464
