Send LeaveEvent as reaction to WM_POINTERLEAVE to reset hover states

Browse Source 
Currently items can get stuck in a hovered state when all fingers are
lifted from a touchscreen. This is because we don't react to the
WM_POINTERLEAVE event from Windows. With this patch we translate a
WM_POINTERLEAVE event to a LeaveEvent to remove the hover state from
QtQuick items.

Fixes: QTBUG-62912
