Browser process scaffolding to support having appcache work in workers.

* Associate a RequestContext with a WorkerProcessHost. This corresponds to themain request context of the profile for which the worker process is running. Also associate the context with each WorkerInstance which comes into existance priorto the WorkerProcessHost that will host the instance.

* Give the WorkerProcessHost an AppCacheDispatcherHost.

* Fix up some recently botched IPC plumbing for ViewHostMsg_CreateWorker_Params.


BUG=39368
TEST=there are no worker unit tests
