Move WorkerThreadLifecycleObserver::contextDestroyed out of SafePointScope

Move WorkerThreadLifecycleObserver::contextDestroyed out of SafePointScope

Oilpan forbids to allocate objects in a SafePointScope. It is too restrictive
for WorkerThreadLifecycleObserver::contextDestroyed, so this CL moves the
WorkerThreadLifecycleContext::notifyContextDestroyed call out of
SafePointScope.
