5b73b80b0d Make shared_relro policy private.
Nothing should be depending on the details.

I haven't removed public/shared_relro.te entirely - there's a reference to shared_relro in public/app.te, and at least one reference to the domain outside of system policy.

Test: Presubmits

7c34e83fcd Move domain_deprecated into private policy
This attribute is being actively removed from policy. Since
attributes are not being versioned, partners must not be able to
access and use this attribute. Move it from private and verify in
the logs that rild and tee are not using these permissions.

Bug: 38316109
Test: build and boot Marlin
Test: Verify that rild and tee are not being granted any of these
      permissions.

f5446eb148 Vendor domains must not use Binder
On PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor
apps) are not permitted to use Binder. This commit thus:
* groups non-vendor domains using the new "coredomain" attribute,
* adds neverallow rules restricting Binder use to coredomain and
  appdomain only, and
* temporarily exempts the domains which are currently violating this
  rule from this restriction. These domains are grouped using the new
  "binder_in_vendor_violators" attribute. The attribute is needed
  because the types corresponding to violators are not exposed to the
  public policy where the neverallow rules are.

Test: mmm system/sepolicy
Test: Device boots, no new denials

Test: Google Camera: take a photo, take an HDR+ photo, record video with
      sound, record slow motion video with sound. Confirm videos play
      back fine and with sound.

3e8dbf01ef Restore app_domain macro and move to private use.
app_domain was split up in commit: 2e00e6373f to
enable compilation by hiding type_transition rules from public policy.  These
rules need to be hidden from public policy because they describe how objects are
labeled, of which non-platform should be unaware.  Instead of cutting apart the
app_domain macro, which non-platform policy may rely on for implementing new app
types, move all app_domain calls to private policy.

2e00e6373f sepolicy: add version_policy tool and version non-platform policy.
In order to support platform changes without simultaneous updates from
non-platform components, the platform and non-platform policies must be
split.  In order to provide a guarantee that policy written for
non-platform objects continues to provide the same access, all types
exposed to non-platform policy are versioned by converting them and the
policy using them into attributes.

This change performs that split, the subsequent versioning and also
generates a mapping file to glue the different policy components
together.

Test: Device boots and runs.
