[proxies] Check for stack overflow when calling through to the target

[proxies] Check for stack overflow in Proxy internal methods

The proxy may be on its own target's or handler's prototype chain, leading
to infinite recursion either when looking up the trap, or when calling
through to the target.
We can't eagerly prevent this from happening (e.g. at "foo.__proto__ = bar"
calling time) because the presence of traps can change at any time.
