Update from https://crrev.com/333737

* Cherrypick crrev.com/333293 (freetype -> freetype-android).
* Update mojo/go/go.py to use android-16 (NDK API level 16), which is
  4.1 (first Jelly Bean). Chromium dropped support for 14.
* TODO (separately): also update tools/go/upload.py and upload new
  binaries?
* Roll android_tools (to match Chromium).
* Small fixes to match //base changes: base::ObserverList, TraceConfig,
  ThreadTicks, etc.
* Restore build/ls.py (and add it to the list of files to not roll).
* Remove the dependency on third_party/instrumented_libraries.
* Add "enable_topchrome_md = false" to build/config/ui.gni.
* Add build/config/ui.gni to files_not_to_roll in
  update_from_chromium.py. (We should probably get rid of the use_glib
  variable/argument, and others as well.)
* Remove mojo/tools/roll/{roll_network_service.py,
  roll_network_service_patches/network_service.patch}. These are for
  rolling from Chromium, whereas we now have/use monet.
* Roll buildtools (to match Chromium).
* Modify sanitizer gn/gni files to make it work (patch included).
  (Maybe the patch even works -- I haven't checked.)
