Measure the frequency of resuming a stopped page

Project Member Reported by fmea...@chromium.org, Oct 30 2017 
On Android, we stop timers queues(and loading queues) after N minutes.
We currently don't track how often the user returns to the backgrounded page causing those timers to resume.

We would like to track this metric since we plan to fire a callback (pagehide) when we stop the page. Will this callback be the final code that can run in a typical case or not?

[PageLifecycle] Add UMA to track when a stopped renderer is resumed

This CL adds UMA metrics to track the states of a renderer when it is
backgrounded.

Once it is backgrounded, it can either resume or stop. If it is stopped
it can also later resume. We are interested in the later case but for
completeness we track all 4 cases.
