Use get_cursor_shape for identifying the cursor shape in AnimationNodeStateMachineEditor

get_cursor_shape() is used in cases where a Control displays different cursors in different areas.
There is no need to set the default cursor shape on every mouse move event.

Fix minor issue with selection order.
