Provide Main Frame latency data to cc The cc metrics system needs a breakdown of the renderer's BeginMainFrame overall latency. Plumb a structure through to LocalFrameView and populate it with the metrics data. We use DidBeginMainFrame because it invokes the post lifecycle steps that include the intersection observer step. Currently missing is code in ProxyMain to set the update layers latency.
