Lasse R.H. Nielsen 8760283247 New implementation of runZoned.
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.
