system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.
Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.
Test: Device boots and no obvious problems.

Add selinux policy for the new Binder-based vr flinger vsync service.
Bug: 72890037
Test: - Manually confirmed that I can't bind to the new vsync service
from a normal Android application, and system processes (other than
vr_hwc) are prevented from connecting by selinux.
- Confirmed the CTS test
android.security.cts.SELinuxHostTest#testAospServiceContexts, when
built from the local source tree with this CL applied, passes.
- Confirmed the CTS test
android.cts.security.SELinuxNeverallowRulesTest#testNeverallowRules521,
when built from the local source tree with this CL applied, passes.

Specify per-service rules for PDX transport. Now being able to
grant permissions to individual services provided by processes,
not all services of a process.
Also tighter control over which permissions are required for
client and server for individual components of IPC (endpoints,
channels, etc).

VR HWC is being split out of VR Window Manager. It creates a HW binder
interface used by SurfaceFlinger which implements the HWComposer HAL and
a regular binder interface which will be used by a system app to receive
the SurfaceFlinger output.
Bug: b/36051907
Test: Ran in permissive mode and ensured no permission errors show in
logcat.
