perf: bail early when traversing non-state (#10654 )

This has a lot of overhead for large lists, and we can at least diminish in the "no state proxy" case by applying a sensible heuristic:
- If the value passed is a state proxy, read it
- If not, and if the value is an array, then bail because an array of state proxies is highly unlikely
- Traverse the first level of properties of the object and look if these are state, if not bail. State proxies nested further down are highly unlikely, too
