After definition hook.
This is useful for intermediate classes to inject logic after the definition was provided without requiring developers to call the parent self::definition()} as it's not obvious by design. The 'intermediate' class is 'MyClass extends IntermediateClass extends moodleform'.
Classes overriding this method should always call the parent. We may not add anything specifically in this instance of the method, but intermediate classes are likely to do so, and so it is a good practice to always call the parent.
