Emilio Cobos Álvarez c27a2129fd Bug 1850293 - Make validity states non-intrinsic. r=smaug
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.
