CHROMIUM: add mock admin policy interface

This make bluez provide the old interface org.bluze.AdminPolicy1 so that
Chrome can still set service allowlist. This should be reverted once
Chrome switches to org.bluez.AdminPolicySet1 and
org.bluez.AdminPolicyStatus1.

The revert task is tracking by b:195717647.
