If the fulfilled policies change without the contents of the target and overlay APKs changing, the idmap for the overlay should be regenerated. This change adds fulfilled policies and enforce overlayable to the idmap header so that idmap2d can determine if the polices or enforce overlayable changed from what was used to generate the idmap. Bug: 119328308 Test: idmap2_tests Test: atest RegenerateIdmapTest Change-Id: I96f970e82b5243be01b205ac2cb6ab249c6100bc
