This is to migrate sepolicy Makefiles into Soong. For the first part, file_contexts, hwservice_contexts, property_contexts, and service_contexts are migrated. Build-time tests for contexts files are still in Makefile; they will also be done with Soong after porting the module sepolicy. The motivation of migrating is based on generating property_contexts dynamically: if we were to amend contexts files at build time in the future, it would be nicer to manage them in Soong. To do that, building contexts files with Soong can be very helpful. Bug: 127949646 Bug: 129377144 Test: 1) Build blueline-userdebug, flash, and boot. Test: 2) Build blueline-userdebug with TARGET_FLATTEN_APEX=true, flash, and boot. Test: 3) Build aosp_arm-userdebug. Change-Id: I49206e656564206d6f7265206361666665696e65
