Define DevTools content API

The API consists of the following parts:
* DevToolsManager routes messages between devtools agents and clients
* DevToolsAgentHost provides an abstract interface to the debuggee, currently it is either RenderViewHost or Shared Worker. Client can obtain DevToolsAgentHost from DevToolsAgentHostRegistry.
* DevToolsClientHost is an API that should be implemented by DevTools front-end. There is a default Chromium implementation living in chrome/ and a remote debugging server which also implements this interface. Clients can extend it in order to provide custom front-end. There is a default DevTools front-end implementation and content/ provides a way for creating corresponding DevToolsClientHost by means of DevToolsClientHost::CreateDevToolsFrontendHost. The embedder just needs to provide a concrete delegate.
* This patch also removes DevToolsHost_ForwardToAgent and DevToolsHost_ForwardToClient IPC messages which were used to forward only one message. DevTools IPC messages are now hidden behind the devtools content API.
