This change adds basic Chrome runtime implementations for CefBrowserContext and CefBrowserPlatformDelegate. A Chrome browser window with default frame and styling can now be created using CefBrowserHost::CreateBrowser and some CefClient callbacks will be triggered via the WebContentsObserver implementation in CefBrowserHostImpl. Any additional browser windows created via the Chrome UI will be unmanaged by CEF. The application message loop will block until all browser windows have been closed by the user.
