Revert Revert "Expose chrome policies using Android's App Restrictions Schema"

Android generates alternate resources when dependent on a higher sdk version then the minsdkversion.
This is conflicts with Playstore rules that only permit one resource for App Restrictions.
I have now qualified the resource to apply only for sdk > 21 where the App Restriction API was exposed.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer,
_not_ a full super star committer.
