Add new latency_info for tracking browser composite time.
RenderWidgetHostImpl maintains a rolling estimate of composite times
to be passed to RenderWidgetHostViewAndroid::SendBeginFrame to
improve deadline estimate.
Latency info is still currently tied to input events. Future patch
should make the latency_info update on a per frame basis.
