This change removes the ability for an overlayable resource to be defined in multiple policy blocks within the same overlayable. This change also changes aapt2 to use a bit mask to keep track of the parsed policies. Bug: 110869880 Bug: 120298168 Test: aapt2_tests Change-Id: Ie26cd913f94a16c0b312f222bccfa48f62feceaa
