AnimationMixer, AnimationPlayer, animation_finished(anim_name: StringName) => animation_finished(anim_name, backwards:bool)

We have .play(), we also have .play_backwards()
Why don't we have backwards in the signal animation_finished?
I can define backwards using current_animation_position, but then why is there a play_backwards?...

I'm not sure if this would be welcome, given this comment: godotengine/godot#89525 (comment)

My PR that adds animation_looped signal adds a backwards parameter to that signal, but I didn't touch animation_finished. Also, I believe adding a new optional argument to a signal breaks compatibility, because signal receiver functions can't be called if too many arguments are passed by the emitter.
