A new module type se_neverallow_test is added, to migrate
sepolicy_neverallow modules. se_neverallow_test is affected by
SELINUX_IGNORE_NEVERALLOWS.

Although it's not needed for Treblized devices, some targets are still
requiring it due to PRODUCT_SEPOLICY_SPLIT := false. To mitigate build
breakage, this change revives the sepolicy module.

For now, contexts modules have been using se_filegroup modules, which
makes the build system logic unnecessarily complex. This change
refactors it to se_build_files modules and normal `android:"path"`
logic.

sepolicy is a module which outputs precompiled sepolicy and performs
permissive domain check on user builds. se_policy_binary module is
updated so it checks permissive domain in user builds.
sepolicy module is removed since we don't need it anymore. Instead,
precompiled_sepolicy is used.

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.

We need to remove any existing files (and the directory) to allow
odrefresh in the VM to re-create them via authfs.
But we don't need, and shouldn't have, any other access to them.

CompOS needs to read the artifacts on authfs that odrefresh has
created and write signature files for them.
(But it no longer needs to create any directories, so removed that.)

If FD use is not allowed, execve(2) returns EACCESS and the process is
killed by SIGSEGV.
Minijail closes any FDs by default and open /dev/null for FD 0-2. For
now, odrefresh doesn't use any FD. But until we could tell minijail to
not create FD 0-2 (which could be arguable), allow the permission.

dex2oat checks $ANDROID_ROOT exist, which is a directory in an authfs
mount. Give it permission to search along the path.
Strictly speaking, this isn't change how dex2oat execute in this
particular case, for now. Functions like LocationIsOnSystemFramework
make sure getenv(ANDROID_ROOT) exists. But either way, for those kind of
location checks, it won't match the mount path in /data/misc/authfs
anyway.

dex2oat currently uses some properties as flags (see
art/libartbase/base/flags.cc). For CompOS, we don't really need such
properties, and actually should avoid global state. So dontaudit
explicitly.

The `__builtin_available` macro is used in used in several libraries in
microdroid, including liblog. The macro internally uses
ro.build.version.{codename,sdk}[1]. This change defines the context for
these properties.
