Added `get_playing_speed` method to AnimationPlayer, returning the actual

playing speed of the animation being played.

As stated in #16550, there is no way to get the playing speed of an
animation. The `playback_speed` property is for the whole AnimationPlayer
node, and the argument passed to `play` method is another scale applied
in top of the AnimationPlayer properties.

Thus, the actual playing speed is AnimationPlayer.speed_scale *
AnimationPlayer.playback.current.speed_scale. If it is not playing, the
method returns 0.
