Cache QState's child states
This is the same type of optimization as that done for transitions in
commit 5d8dcd57cd13fdd9c8643fa3bdda9f197a4351ff. The idea is to avoid
calling qobject_cast() because it's very expensive.
Obtaining child states needs to be as fast as possible because it's in
the critical path of the state machine algorithm; it's called by a ton
of internal functions, like isCompound(), isAtomic(), isInFinalState().
It's also called heavily for parallel state groups.
