That code wasn't removed - it was just moved out of WorkerScriptController
(since it's not needed for SharedWorkers) and into DedicatedWorkerContext.

The original mechanism to shutdown orphaned workers still works - the problem
is that when we added async APIs to WorkerGlobalScope (setTimeout(), XHR) we
didn't add any additional mechanism to report pending activity when those async
processes ended.
