Add some more IPC plumbing and scaffolding to support having appcache work in workers. Everything is still stubbed out at runtime (runtime feature is still disabled in the worker process, and the values in the IPC messages are all zero'd out).

* Widen the CreateWorker IPC message sent from the browser to the worker process to contain additional data needed to initialize an appcache for that worker.

* Add a new worker specific WorkerWebApplicationCacheHostImpl class and instantiate one with the initialization data received in the IPC.

* Give the WorkerThread an AppCacheDispatcher.

* Propagate the cmd-line argument to disable the appcache to the worker process.

* Fixup DEPs to show that chrome/workers depends on webkit/appcache
