GDScript: Call static methods in native base class

[rune-scape]

allows calling the static methods of the native base on a gdscript object at runtime

fixes #111021

Sorry for delay. Could you use an already existing static method for the test? For example, JSON.stringify().

class MyJSON extends JSON:
    pass

func test():
    print(MyJSON.stringify("test"))

@dalexeev done, didn't find that in my initial search for existing static methods

Looks good to me. 👍 Just a few code style changes. Sorry for the long wait.
