Require READ_PHONE_STATE for DO/PO dev ID access

When device identifier access was moved from a runtime permission to a
privileged permission device and profile owner access regressed by no longer
requiring consent to access the identifiers. With this change device and
profile owners will still need to have the READ_PHONE_STATE permission to
access identifiers.
