Add/Pull a CIPD package that holds AFDO profiles.

Scrubbed Chrome OS profiles (well, one at the moment) live in
chrome/android/profiles. Hopefully we won't need to scrub them soon.

In order to do AFDO on Chromium, we need to pull them locally.

size wins are observed as with unscrubbed profiles on Chrome.apk
(assuming the profile actually gets turned on, which is moved to
another patch).

Bug: 794750
Test: ChromePublic.apk builds after `gclient sync`. Similar perf/binary
