This change moves the runtime-specific implementations of CefBrowserHostImpl methods to CefBrowserPlatformDelegate. Some WebContentsDelegate methods implemented by CefBrowserHostImpl set state or trigger client callbacks. Those implementations will likely stay with CefBrowserHostImpl and will need to be called from the Browser equivalents when using the Chrome runtime.
