26b2d2e33e Add dontaudit statements to camera HAL policy. 
The autogenerated dontaudit statements in tracking_denials are
actually the correct policy. Move them to the correct file and
add comments.

e95f5edafe Allow camera HAL and GCA to access Aurora GXP device. 
The camera HAL and Google Camera App
need selinux permission to run workloads on Aurora DSP. This
change adds the selinux rules too allow these clients to
access the GXP device and load firmware onto DSP cores
in order to execute workloads on DSP.

Bug: 220086991
Test: Verified that the camera HAL service and GCA app is able to access the GXP device and load GXP firmware.

3884738538 Camera: re-add TEE access. 
Face auth is being investigated for Android T, so this access
is still needed. It was initially omitted from ag/16719985 because
it did not launch in Android S.

The camera HAL needs to increase the priority of some threads
to reduce frame drops.

b76b5e3872 Add camera HAL sepolicy based on previous chip family. 
The camera HAL code is reused from the previous chip and needs to
perform the same operations as previously, with the following
differences:
- The interrupt affinity workaround may no longer be necessary
  due to image sensor changes, so the ability to set interrupt
  affinity is removed.
- Access to some files that were only present before the APEX
  migration is removed.
- vendor_camera_tuning_file is no longer needed.
- TEE access for face auth is removed for now.
