Treble sepolicy tests check whether previous versions are compatible to
ToT sepolicy or not. treble_sepolicy_tests_for_release.mk implements it,
but it also includes a compat test whether ToT sepolicy + {ver} mapping
+ {ver} plat_pub_versioned.cil can be built together or not. We
definitely need such tests, but we already have a test called "compat
test" which does exactly that, and testing it again with Treble sepolicy
tests is just redundant. The only difference between those two is that
Treble sepolicy tests can also test system_ext and product compat files,
which was contributed by a partner.
The ultimate goal here is to migrate *.mk to Soong, thus merging these
two tests (compat, Treble) into one. As we've already migrated the
compat test to Soong, this change removes the compat test part from
treble sepolicy tests. Instead, the compat test will be extended so it
can test system_ext and product compat files too.
prebuilts/api/{ver}/plat_pub_versioned.cil and
prebuilts/api/{ver}/vendor_sepolicy.cil are also removed as they aren't
used anymore: vendor_sepolicy.cil is an empty stub, and
plat_pub_versioned.cil can be built from the prebuilt source files.

The bootchart problem need the selinux policy fix.
But it is missing API 32

Like we do with cgroup_v2, we set attribute permission to cgroup
as well.
This is the same fix as
https://android-review.googlesource.com/c/platform/system/sepolicy/+/1927857/
but it applies it to the prebuilts for api 32.0.
Test: On a Go device, which uses cgroup instead of cgroup_v2

Treble doesn't support T system + O vendor, so removing 26.0 (N) and
27.0 (O) prebuilts and compat files.

Steps taken to produce the mapping files:
1. Add prebuilts/api/32.0/plat_pub_versioned.cil from the
/vendor/etc/selinux/plat_pub_versioned.cil file built on sc-v2-dev with
lunch target aosp_arm64-eng. Add prebuilts/api/32.0/vendor_sepolicy.cil
as an empty file.
When adding plat_pub_versioned.cil, leave only type and typeattribute
statements, removing the other statements: allow, neverallow, role, etc.
2. Add new file private/compat/32.0/32.0.cil by doing the following:
- copy /system/etc/selinux/mapping/32.0.cil from sc-v2-dev
aosp_arm64-eng device to private/compat/32.0/32.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 32 sepolicy.
Find all such types using treble_sepolicy_tests_32.0 test.
- for all these types figure out where to map them by looking at
31.0.[ignore.]cil files and add approprite entries to 32.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_32.0 and installs
32.0.cil mapping file onto the device.
