PageLoadMetrics renderer and browser implementation.
This change addresses issues with lost UMA data, by pushing UMA metrics
to the browser process over IPC.
In the render process, we implement a RenderFrameObserver that attaches
to top-level frames, and pushes interesting document timing metrics to
the browser process.
In the browser process, we implement a WebContentsObserver that
receives the document timing metrics and UMA logs them. We implement
WebContentsObserver because, in a future change, we'll start observing
page close events in order to log cases where a page load is aborted
before a layout occurs.
See https://docs.google.com/document/d/1HJsJ5W2H_3qRdqPAUgAEo10AF8gXPTXZLUET4X4_sII/edit for additional details.
