This change provides initial support for sending DevTools messages between Worker and Page processes.

On the Page side devtools messages are handled by WorkerDevtoolsAgentProxy. It implements WebWorkerBase::DevToolsDelegate interface which isolates worker stuff under content/ from DevTools specifics.

In the worker process it's WorkerDevtoolsAgent that is responsible for sending/receiving devtools messages. It implements WebWorkerStub::DevToolsDelegate and WebWorkerClientProxy::DevToolsDelegate which insulate worker stuff under content/ from the devtools implementation details.

WorkerDevtoolsAgentProxy and WorkerDevtoolsAgent are counterparts of WebWorkerProxy and WebWorkerStub. Since devtools is not a part of HTML5 the new classes live under chrome/

ContentWorkerClient is introduced for notifying embedder about certain events when worker clients can be installed.
