[ServiceWorker] Make Stream support in ServiceWorkerURLRequestJob
In ServiceWorkerURLRequestJob::DidDispatchFetchEvent(), if response.stream_url of ServiceWorkerHostMsg_FetchEventFinished is set, ServiceWorkerURLRequestJob starts reading the body of the response from the stream instead of the blob.
But the stream may not be registered yet.
It is because ServiceWorkerHostMsg_FetchEventFinished is sent from the worker thread but StreamHostMsg_StartBuilding which triggers the stream registration is sent from the main thread of the ServiceWorker process.
So if ServiceWorkerURLRequestJob can't get the stream in DidDispatchFetchEvent(), call StreamRegistry::SetRegisterObserver() to receive the stream registration event.
When ServiceWorkerURLRequestJob successfuly gets the stream, it starts reading the stream.
The codes for reading the stream is almost same as the codes in StreamURLRequestJob.
This change depends on these changes:
