This CL adds the SELinux permissions required to execute
atrace and get userspace tracing events from system services.
This is to enable tracing of events coming from surfaceflinger,
audio HAL, etc.
atrace, when executed, sets a bunch of debug.atrace. properties
and sends an IPC via binder/hwbinder to tell the services to
reload that property.

This CL does NOT affect systrace. In that case (i.e. when
atrace is executed from adb/shell) atrace still runs in
the shell domain and none of those changes apply.

This changes tracefs files to be default-enabled in debug mode, but
default-disabled with specific files enabled in user mode.

Bug: 64762598
Test: Successfully took traces in user mode.

(cherry picked from commit b8d14dc9a6b1593c4ad5210f3079bcac3a9aea33)

One of my previous commits removed this, so I am now restoring it.

This commit also contains a bit of cleanup from previous commits by
removing some unneeded types.

It also fixes traceur by porting ag/2409144 to master.

Bug: 62413700, 62547086
Test: Built, flashed, and booted Marlin.  Verified that the files have
the correct context.  Verified that atrace and traceur work.

Service boottrace runs atrace out of shell context for tracing during
boot. Therefore, we need the same permission set in shell.te to run atrace
in boottrace service.

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: In Chrome, navigate to ip6.me, play a YouTube video
Test: YouTube: play a video
Test: Netflix: play a movie
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.

atrace and its atrace_exec now exist only in private policy.

Test: No change to policy according to sesearch, except for
      disappearance of all allow rules to do with atrace_current
      which is expected now that atrace cannot be referenced from
      public or vendor policy.

Make all platform tyeps public to start to prevent build breakage in any devices
that may have device-specific policy using these types.  Future changes will
need to be carefully made to ensure we properly limit types for use by
non-platform policy.

Test: Builds

Divide policy into public and private components.  This is the first
step in splitting the policy creation for platform and non-platform
policies.  The policy in the public directory will be exported for use
in non-platform policy creation.  Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.

Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal.  For now, almost all types and
avrules are left in public.

Test: Tested by building policy and running on device.

The label for /sys/kernel/debug/tracing was changed from debugfs
to debugfs_tracing in commit https://android-review.googlesource.com/187692 .
Ensure we're using the correct label.

Motivation: Domain is overly permissive. Start removing permissions
from domain and assign them to the domain_deprecated attribute.
Domain_deprecated and domain can initially be assigned to all
domains. The goal is to not assign domain_deprecated to new domains
and to start removing domain_deprecated where it is not required or
reassigning the appropriate permissions to the inheriting domain
when necessary.
