Convert ChromeSyncShell to use ChromePublic infrastructure (try #2)

Convert ChromeSyncShell to use ChromePublic infrastructure (try #2)

This is a re-land of the patch originally committed as part of
https://codereview.chromium.org/1282603005/. The one major change is
that a landmine has been added to clobber the Android arm64 bot as it
caused problems after the original commit.

Several test fixes are included to support this change.

Note: This CL only provides a GYP implementation (no GN). This is not a
regression from the previous state.
