Added beginnings of browser-process support for shared workers.

Refactored WebWorkerClientProxy into two classes - WebWorkerDispatcher which dispatches incoming IPCs for the worker, and WebWorkerClientProxy, which handles outgoing API calls from WebWorkerImpl. This allows WebWorkerClientProxy to be reused by WebSharedWorkerDispatcher.

BUG=26233
TEST=none (will enable layout tests when basic functionality available)
