Add “isSubmitting” in useController().meta

Is your feature request related to a problem? Please describe.
I’m currently wrapping my controller with a “Smart Form Component”. In this case, my formState is inside another component, which my controller input can’t access. In order to make my controller input able to disable according to the is Submitting flag, would like to request for adding it in useController().meta
