Secondary dex files are in app data directories. In order to perform
secondary dex compilation, artd needs permissions to:
- Read secondary dex files
- Create "oat" dir
- Create a reference profile in "oat" dir
- Rename the reference profile
- Delete the reference profile
- Read the current profile in "oat" dir
- Delete the current profile
- Create compilation artifacts in "oat" dir
- Rename compilation artifacts
- Delete compilation artifacts

Remove references in sepolicy. Leave a few of the types defined since
they're public and may be used in device-specific policy.

It only accesses already-open file handles since b/67111829, so has no
need for any access to the directories, not even search access.

We have various apps which inherently work across all users,
configured in seapp_contexts with levelFrom=None (usually implicitly).
This change marks those apps, where they have private data files, as
mlstrustedsubject, to allow us to increase restrictions on cross-user
access without breaking them.
Currently these apps are granted full access to [priv_]app__data_file
via TE rules, but are blocked from calling open (etc) by mls rules
(they don't have a matching level).
This CL changes things round so they are granted access by mls, but
blocked from calling open by TE rules; the overall effect is thus the
same - they do not have access.
A neverallow rule is added to ensure this remains true.
Note that there are various vendor apps which are appdomain,
levelFrom=None; they will also need modified policy.
Test: builds, boots, no new denials.
