Mouse: add function to move to and click something

[NathanLovato]

Add a simple API to have the mouse move and click on something, with automated direction and placement.

Similar to how we use animated pointers in videos on YouTube, short motion, ease in on target, + click animation at end.

The function signature could be like: mouse_move_and_click(target_position: Vector2, from_distance := 80.0, direction := MouseDirection.AUTO)

Note: the distance should maybe auto-scale with editor scale.

The mouse direction can be calculated from the editor window and distance to bounds.

This could rely on a new extra function mouse_move_to(target_position: Vector2) function + the existing mouse_click().
