QCursor: Associate cursor with screen.

- Introduce cursor() accessor to QPlatformScreen.
- Remove screen member of QPlatformCursor (a
  cursor can be shared by multiple screens
  of a virtual desktop).
- Add QCursor::pos()/ QCursor::setPos() taking
  a QScreen-parameter, use primaryScreen() for
  old overloads.  QCursor::pos() can then query
  the platform cursor for the position and return
  the position even if the mouse position is outside
  the windows owned by the Qt application.
- Fix tests
