Fix a bug where hover events were not sent if the mouse was never moved

This happened if the "real mouse" was never moved, since moving the real
mouse caused it to update the internal
QQuickWindowPrivate::lastMousePosition. If the window never got any
mouse events, it would therefore fail to generate proper hover events.
However, if the window got exposed under a mouse cursor it would generate
a hover enter event. We therefore update lastMousePosition when that
happens also.
