Like zygote, webview_zygote, add userfaultfd policy for app_zygote as
well.

Test: manual (use userfaultfd in an app-zygote)

The binder driver now advertises the features it supports through
individual files under /dev/binderfs/features/*. Let all domains have
access to these files to determine how to interact with the driver.
Bug: 191910201
Tested: clients are able to read feature files via libbinder

Allow crosvm to write a VM failure reason to virtualizationservice via the pipe provided.
Fixes this denial: avc: denied { write } for path="pipe:[95872]"
dev="pipefs" ino=95872 scontext=u:r:crosvm:s0
tcontext=u:r:virtualizationservice:s0 tclass=fifo_file
Bug: 220071963
Test: Run VM, no denial.

This is intended for wm properties related to wmshell/sysui.
Using this context allows sysui to manipulate these properties
in debug builds.

This is necessary for vendor code to be able to send trace packets to
Perfetto, which we are doing as part of an effort to provide more
detailed profiling of some vendor code.

This is useful for certain tests. Note that it is already possible to
access these files without root via adb pull, since adbd has
access. Shell also already has access to non-updated APEXes on
/system/apex.
Bug: 220918654
Test: adb unroot; pm install --apex /data/apex/decompressed/X.decompressed.apex

perfetto traced_probes executes atrace with a pipe for stdout/stderr.
That aleady works because atrace can `write` onto traced_probes's pipes.
Now traced_probes needs to invoke atrace at boot time. This revealed a
problem (I'm pretty sure it was an existing problem and it was
completely harmless):
```
02-23 22:00:41.951 605 605 I auditd : type=1400 audit(0.0:94): avc:
denied { getattr } for comm="atrace" path="pipe:[17964]" dev="pipefs"
ino=17964 scontext=u:r:atrace:s0 tcontext=u:r:traced_probes:s0
tclass=fifo_file permissive=0
```
atrace doesn't just need `write` permissions on its
stdout/stderr pipes, it also needs `getattr` permissions (probably
because of [this][1]?)

Any virtualization service client should be able to use a pipe for the
VM log fds.
We previously had some support for this in crosvm (but appdomain is
the wrong label), but not for virtualizationservice. Instead I've
centralised it in the virtualizationservice_use macro so it applies to
exactly those things that can start a VM.
I've removed read permission from crosvm; it doesn't seem to be
needed, and logically it shouldn't be.
Test: Patch in https://r.android.com/1997004, see no denials

CompOS no longer talks directly to DICE (compos_key_helper does). odsign
no longer promotes or deletes instance CompOS files, and the key files
don't exist any more.

Add the compos_key_helper domain for the process which has access to
the signing key, make sure it can't be crashdumped. Also extend that
protection to diced & its HAL.
Rename compos_verify_key to compos_verify, because it doesn't verify
keys any more.
Move exec types used by Microdroid to file.te in the host rather than
their own dedicated files.
