add UKM recorder measuring when pages load with an appcache manifest

Project Member Reported by wanderview@chromium.org, Sep 12

Issue description

To help the migration from appcache to service worker we would like to know when pages load using appcache.  To that end we'd like to add a UKM recorder similar to this SW recorder:

https://cs.chromium.org/chromium/src/chrome/browser/page_load_metrics/observers/service_worker_page_load_metrics_observer.cc?l=402&rcl=8b9b95d27975aa1d19476c54e75f2c630c38f4b7

I have requested approval to add this metric.  Once that is approved I can write a CL.

I have privacy approval.

I started looking at the code, though, and its a bit harder than I anticipated.  The appcache system is not activated unless the tab is offline.  We really want to record for online pages that would use appcache if offline.  I don't think this information is available in the renderer at the moment.

Victor said he would take this one since he is working on some other appcache stuff as well.
