Update histogram owners for some Tab* histograms.

I noticed that Tab.NewTab was owned by two people, neither of
whom work on Chrome anymore (beaudoin@ and lliabraa@). This
CL attempts to clean up ownership. New owners are encouraged
to review the histograms they are now owning and clean up any
that are not useful and/or add expiry dates to evaluate later.

Here's the logic used for assigning owners:

NTP histograms: kmilka@chromium.org, ramyan@chromium.org
Desktop Tab histograms: tbergquist@chromium.org, bsep@chromium.org
iOS Tab histograms: marq@chromium.org
Android Tab histograms: dtrainor@chromium.org
Android stability histograms: wnwen@chromium.org

For already-obsolete histograms, I just removed the two people
who were owners of Tab.NewTab who don't work on Chrome anymore
instead of finding replacements.

Please let me know if you have better suggestions for owners.
Also, having more than one owner is encouraged, so consider
adding others in a follow-up CL or as suggestions on this CL.

Also adds [Android] and [iOS] tags to histograms that are only
logged on those platforms and marks a few <obsolete> that are no
longer in the codebase.
