[TTS] Add more user engagement signals for Ranker for Contextual Search

Project Member Reported by donnd@chromium.org, May 29 2018 
We'd like to know more about *users* in order to improve Tap Suppression for Contextual Search.  This is obviously potentially privacy-sensitive, so for now we propose adding engagement features, since those are likely to be relatively privacy safe, and also useful in predicting future engagement.

Specifically we'd like to add the all-time count of panel opens for Contextual Search, the number of Quick Actions taken, the number of Quick Actions presented, the number of entities presented in the Bar, and the number of "Quick Answers" (which all tend to be translations in Bar), and maybe some other similar metrics.

I plan to start another round of UKM metrics additions to document this in go/ukm-cs-4.

Landed CL for this: https://chromium-review.googlesource.com/1079810

[TTS] Add an engagment Heuristic for ML Tap work.

Adds an Engagement Suppression heuristic that sends several new signals
to the ML model for Tap Suppression.  These signals quantify user
engagment by registering the number of lifetime opens, quick actions
taken, translations shown, etc.

Note that the additional signals in this CL are documented in
http://go/ukm-cs-4 (with privacy approval noted there).
