To make it easier to add the actor policy in a follow up CL, move most of the policy handling to a central location. The strings and transformation between strings and flags is now handled in libidmap2policies, with libandroidfw containing the single source of policy flags. This also extracts all the test resource IDs into an R.h so they can be swapped without having to edit a dozen files each time. Bug: 130563563 Test: m aapt2_tests idmapt2_tests and run from host test output Test: atest libandroidfw_tests Change-Id: Ie533c9cebf938215df7586f00c38763ae467e606
