[ServiceWorker] Add worker lifecycle status to ServiceWorkerRunningInfo.

We'd like to make the lifecycle status available to the //extensions
layer so we can log it for debugging purposes. We suspect it might be a
factor in the cause of why we are registering multiple workers (which is
normal for web service worker, but not expected for extension service
workers).
