Add QStateMachine constructor that takes a ChildMode

Back when QStateMachine was changed to inherit QState, this
constructor was conveniently left out because setting the state
machine (root state) to be a parallel state group didn't actually
work. But as of commit d281aa6936ad01e28dacabb41bd9eb59891f85a1,
it does work, so add the missing constructor.
