Swaps the TrackedPoseDriver over to using InputActionProperty's

[mattdatwork]

Swaps the TrackedPoseDriver bundled with the new input system to use InputActionProperty's rather than InputActions.

This also includes an updated test which passes locally.

Tested locally with oculus quest.

As discussed with @mattdatwork, breaks backwards-compatibility both at serialization and API level. Looks like neither is something we can do at this point.
