Teaches idmap2 to recognize policy restrictions put on overlayable resources. If overlayable enforcement is turned on for an overlay, then any resources defined within the overlayable api of the target will have policy restrictions imposed on them. All resources without overlayable definitions will continue to be overlayable without policy restrictions. Bug: 119390857 Test: atest idmap2 and booting Co-authored-by: Ryan Mitchell <rtmitchell@google.com> Change-Id: I7e435648eb6e4a87b0b90a7b2a0c3f33c1516ea6
