fix: don't reuse proxies when state symbol refers to stale value (#10343 )

* fix: don't reuse proxies when state symbol refers to stale value

When somebody copies over the state symbol property onto a new object (you can retrieve the symbol by using `Reflect.ownKeys(...)`), it was wrongfully assumed that it always relates to the current value. This PR adds an additional check that this is actually the case.
This also adds a dev time warning when an object is frozen but contains a state property, which hints at a bug in user land.
