[w3c/ServiceWorker] Find a way for service workers to get their current state (#1077)

A service worker instance currently has no way to get it's current lifecycle state. There's a bit of a hack one can do where you keep track of the current event as a global variable but that's error prone and doesn't capture the waiting periods correctly.

Imo, the best way to solve this would be to just allow a service worker to get it's ServiceWorker object somehow. Maybe via `self.worker` or `self.self` or something like that.
