Steps taken to produce the mapping files:
0. Add 33.0 prebuilts to prebuilts/api/33.0/.
1. Add the following Android.bp modules.
33.0.board.compat.map
33.0.board.compat.cil
33.0.board.ignore.map
plat_33.0.cil
system_ext_33.0.cil
product_33.0.cil
33.0.ignore.cil
system_ext_33.0.ignore.cil
product_33.0.ignore.cil
33.0.compat.cil
system_ext_33.0.compat.cil
2. Touch the following three files.
private/compat/33.0/33.0.cil
private/compat/33.0/33.0.compat.cil
private/compat/33.0/33.0.ignore.cil
3. Add 33.0 to PLATFORM_SEPOLICY_COMPAT_VERSIONS on
build/make/core/config.mk. Note that we don't update
sepolicy_major_vers to 33, but just update compat versions.
4. Run the following command.
$ source build/make/rbesetup.sh && lunch aosp_arm64-userdebug
$ m sepolicy_generate_compat
$ sepolicy_generate_compat --branch=tm-dev \
--build latest --target-version 33.0 \
--latest-version 32.0
This change also enables treble_sepolicy_tests_33.0 and installs
33.0.cil mapping file onto the device.
Test: m treble_sepolicy_tests_33.0
Test: m 33.0_compat_test
Test: m slinux_policy

se_build_files is a replacement for se_filegroup module. se_build_files
can be used with the normal Soong convention ":module_name{.tag}" by
implementing android.OutputFileProducer. It's better than implementing
ad-hoc logics across various modules, which is the case for se_filegroup
module.
Test: build and boot

compat_test tests whether {ver}.compat.cil is compatible to current
policy or not. This commit migrates all tests into a single module named
"sepolicy_compat_tests".
A minor issue is also resolved with this migration. Suppose that the
vendor's speolicy version is {VER}. Then the following cil files are
compiled in runtime.
- system/etc/selinux/plat_sepolicy.cil
- system/etc/selinux/mapping/{VER}.cil
- system/etc/selinux/mapping/{VER}.compat.cil (optional)
- system_ext/etc/selinux/system_ext_sepolicy.cil (optional)
- system_ext/etc/selinux/mapping/{VER}.cil (optional)
- system_ext/etc/selinux/mapping/{VER}.compat.cil (optional)
- product/etc/selinux/product_sepolicy.cil (optional)
- product/etc/selinux/mapping/{VER}.cil (optional)
- product/etc/selinux/mapping/{VER}.compat.cil (optional)
- vendor/etc/selinux/vendor_sepolicy.cil
- vendor/etc/selinux/plat_pub_versioned.cil
- odm/etc/selinux/odm_sepolicy.cil (optional)
That is, the vendor policy of version {VER} (vendor_sepolicy.cil,
plat_pub_versioned.cil, and odm_sepolicy.cil) is required to be
compatible only to {VER}.compat.cil. So, the vendor policy is included
only to $(BOARD_SEPOLICY_VERS)_compat_test. The other tests will be
built only with platform side policies.

Test: boot
Test: manually edit {ver}.compat.cil files and try build

Because Android.bp is getting bigger and bigger.
Test: build and boot
Test: set OVERRIDE_TARGET_FLATTEN_APEX=true and build
