RootMotionView methods are missing

[vonagam]

Had 4 inconsistencies that i found during writing bindings. With get_name in EditorSpatialGizmoPlugin, rotate in PathFollow2D, light_mask in LightOccluder2D and missing getter/setters in RootMotionView.

First three problems seem to be solved in godot 4 with proper renames, but RootMotionView issue still remains:

RootMotionView has 4 properties defined with getters and setters, but none of those getters or setters are present in api (json or documentation).

#90 is a duplicate, but now has some details provided, so closing in its favor.
