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.

-// Developer tools consist of the following parts:
-//
-// DevToolsAgent lives in the renderer of an inspected page and provides access
-// to the pages resources, DOM, v8 etc. by means of IPC messages.
-//
-// DevToolsClient is a thin delegate that lives in the tools front-end
-// renderer and converts IPC messages to frontend method calls and allows the
-// frontend to send messages to the DevToolsAgent.
-//
-// All the messages are routed through browser process. There is a
-// DevToolsManager living in the browser process that is responsible for
-// routing logistics. It is also capable of sending direct messages to the
-// agent rather than forwarding messages between agents and clients only.
-//
-// Chain of communication between the components may be described by the
-// following diagram:
-//  ----------------------------
-// | (tools frontend            |
-// | renderer process)          |
