This isn't something I've encountered in any wiring diagrams that I've ever looked at, though it could be a capability offered in different national markets. It strikes me as the sort of thing you'd have to create yourself, and with a bit of electrical knowledge.
My immediate thoughts on the subject are that it would probably be difficult to find or create an electrical signal which says that the Forester was going above a particular speed. What might be easier to handle would be to set up a circuit that would pulse the lock button after the key is turned on, either immediately or after a brief time delay. This should accomplish pretty much what is intended of the first half of the application, locking the doors. A similar circuit could then unlock them when the key is shut off.
A bit of CMOS circuitry, a few transistors, a couple of relays, a few discrete components, knowing how to hook them together ...
