[V8] Use toV8() for wrapping objects in a WorkerContext

Summary
[V8] Use toV8() for wrapping objects in a WorkerContext

The main thing this requires is checking for the existence of a WorkerContextExecutionProxy in V8DOMWrapper::instantiateV8Object() prior to checking for a V8Proxy, since calling V8Proxy::retrieve() in a WorkerContext will crash us.

patch This looks great! Except:

Are you sure this doesn't affect performance?

I ran the dromaeo tests locally and the results were comparable with and without the change. If there's anything else you'd like me to run, please let me know :)
