Add a RAII helper to notify of multiple state changes together for these. The UpdateState CustomElementInternals calls that are getting removed are unnecessary (the state should be up-to-date by then, there's nothing changing there particularly). Same for the call in nsGenericHTMLFormElement::UnbindFromTree. ClearForm already does an state update. Differential Revision: https://phabricator.services.mozilla.com/D187033
