A combination of `runZoned` and `runZonedGuarded` where only the latter allows an `onError` parameter, and only that has a nullable return type. Retains the `onError` parameter on `runZoned` for now because it's too breaking to remove it until packages have been migrated off of it. It will be removed in a follow-up CL.
