Get rid of having users dispatch control runnables. It was error prone and
required too much reasoning. It was also possible to end up in a state where
callers would dispatch a WorkerRunnable, which would succeed, so they would not
dispatch a WorkerControlRunnable. Then the worker would stop Running,
canceling and releasing the runnable leading to releasing the proxy in an
unclean state. Instead, we AddRef() and add the feature and remove the feature
and Release() on Notify(). If callers successfully run a WorkerRunnable they
clean the proxy. If not, the proxy stays alive until the worker switches to
Canceling state.
client.focus() now directly uses the DOMServiceWorkerFocusClient event. The
platform popup checking is not available on service workers. Instead each
worker maintains a counter of if it is allowed to interact with windows. This
counter is currently only incremented by the notificationclick event and
dropped after the event has been dispatched.
Since acquiring a client is an async operation most service workers will
perform in notificationclick, an additional extension is granted after the event
during which the service worker may focus a client. This extension is only granted
if the script invokes NotificationEvent.waitUntil() at which point the timer begins.
The extension is terminated when the Promise passed to waitUntil() is fulfilled, or
the timer expires, whichever comes first.

Without this, ServiceWorker::PostMessage won't work when the window has
been cleaned up, since at that time the event targets are disconnected
from their owners and GetParentObject() will return null.
