Fix Any state transitions will be created from SSMs:

- Due to an implementation error, creating Any state transitions previously did not have any effect in the graph.
- This now creates Any state from the root machine.
- Sub-state machines "cannot" have Any state transitions created directly from them.
- Internally, Any always comes from the root state machine, but visually in the graph, it will come from the sub-state machine.
