This is a partial revert of commit 8267208921.
The previous commit removed a public type, which is a version-incompatible
change to the SELinux vendor API. Since the 2017 devices are meant to be
launching with the previous version, this is unacceptable. Revert the
version-incompatible parts of the change, but keep the other parts to enable
existing system functionality to persist and become part of MR1. Leave TODOs
to remove the other parts when a version bump is acceptable.
Bug: 38241921
Test: Policy builds and device boots with ASAN enabled.
