plat_sepolicy_vers.txt stores the version of vendor policy. This change
adds sepolicy_vers module to migrate plat_sepolicy_vers.txt to

- Device's plat_sepolicy_vers: should be BOARD_SEPOLICY_VERS
- Microdroid's plat_sepolicy_vers: should be PLATFORM_SEPOLICY_VERSION

This reverts commit d869d02758.
Reason for revert: fixed breakage
The breakage was due to the difference between plat_sepolicy.conf and
microdroid_vendor_sepolicy.conf. Now vendor_sepolicy.conf is built with
se_policy_conf module, so it is synced with plat_sepolicy.conf

This replaces the following policy files with Android.bp modules:

- system_ext_sepolicy.cil
- product_sepolicy.cil

- system_ext_pub_policy.cil
- pub_policy.cil

se_build_files module globs given srcs from sepolicy directories and
acts as a filegroup with the following tags, which can be used to build
system side policy files.
- plat
- plat_public
- system_ext
- system_ext_public
- product
- product_public
- reqd_mask
se_build_files module acts like the build_policy macro in Android.mk.
Normal genrule module can't easily handle that, because both file order
and directory order matter.
Support for vendor/odm is to be added in the future.
Bug: 33691272

build_sepolicy internally uses other tools like checkpolicy and
version_policy. The dependencies are used to be found under
out/host/linux-x86/bin. But that assumption doesn't hold when soong
tried to sandbox command invocations. This change fixes the problem by
setting --android_host_path to the directory where build_sepolicy is
sandboxed and also by adding the internal dependeicies to the `tools`
property so that they are copied to the sandbox directory.

microdroid_vendor is the vendor.img for microdroid. We need
microdroid_vendor.img and sepolicy files in it because init demands the
files during the boot process. Since microdroid_vendor.img is a Soong
module, the sepolicy files in it should be built with Soong as well.
Note that, these Soong modules are configured only for microdroid. In
the future, we will generalize this so that ordinary Android can use
the Soong-build sepolicy files.

Steps taken to produce the mapping files:
1. Add prebuilts/api/30.0/plat_pub_versioned.cil from the
/vendor/etc/selinux/plat_pub_versioned.cil file built on rvc-dev with
lunch target aosp_arm64-eng. Add prebuilts/api/30.0/vendor_sepolicy.cil
as an empty file.
2. Add new file private/compat/30.0/30.0.cil by doing the following:
- copy /system/etc/selinux/mapping/30.0.cil from rvc-dev aosp_arm64-eng
device to private/compat/30.0/30.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 30 sepolicy.
Find all such types using treble_sepolicy_tests_30.0 test.
- for all these types figure out where to map them by looking at
29.0.[ignore.]cil files and add approprite entries to 30.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_30.0 and installs
30.0.cil mapping file onto the device.

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.

New maintenance scheme for mapping files:
Say, V is the current SELinux platform version, then at any point in time we
only maintain (V->V-1) mapping. (V->V-n) map is constructed from top (V->V-n+1)
and bottom (V-n+1->V-n) without changes to previously maintained mapping files.
Caveats:
- 26.0.cil doesn't technically represent 27.0->26.0 map, but rather
current->26.0. We'll fully migrate to the scheme with future releases.

With project Treble, we're relying heavily on attributes for
permission inheritance and enforcement of separation between
platform and vendor components.
We neead tests that verify those attributes are correctly applied.
This change adds the framework for those tests including a wrapper
around libsepol for loading and querying policy, and a python module
for running tests on policy and file_contexts.
Included with the testing framework is a test asserting that the
coredomain attribute is only applied to core processes. This
verification is done using the following rules:
1. Domain's entrypoint is on /system - coredomain
2. Domain's entrypoint is on /vendor - not coredomain
3. Domain belongs to a whitelist of known coredomains - coredomain
In a subsequent commit these tests will be applied at build time.
However, I first need to fix existing Treble violations exposed by
this test. These tests will also be applied during CTS.
