Issue descriptionWe should add PageLoad.Clients.PreviewsResourceLoadingHints.* UMA to help in better understanding and debugging resource loading hints performance benefits. We should at least add the metrics that track the time taken from Navigation start to: FCP, FMP, DomContentLoaded, LoadEventFired.
