Add teleport(StringName to_node) to AnimationNodeStateMachinePlayback

Currently, one of the things you lose when connecting an AnimationTree's state machine to an AnimationPlayer is the ability to directly control the active animation. If travel() is called several times in the same frame, only the final value is used, leading to the inability to control certain types of animations. This is especially limiting when cycles should be interrupted (thrown back into some starting state), but calling travel('initial_state') and then travel('goal_state') means that the initial call is essentially ignored.

Godot should expose a teleport() method directly to the user allowing them to immediately set the current state of the machine to a particular node.

I'm reading more about AnimationNodeStateMachinePlayback to try to work around this... maybe start() is effectively a teleport?

Yep, appears to work as I would expect teleport to work. Scratch this suggestion, already done!
