Remove some allow rules for odsign, since it no longer directly
modifies CompOs files. Instead allow it to run compos_verify_key in
its own domain.
Grant compos_verify_key what it needs to access the CompOs files and
start up the VM.
Currently we directly connect to the CompOs VM; that will change once
some in-flight CLs have landed.
As part of this I moved the virtualizationservice_use macro to
te_macros so I can use it here. I also expanded it to include
additional grants needed by any VM client that were previously done
for individual domains (and then deleted those rules as now
redundant).
I also removed the grant of VM access to all apps; instead we allow it
for untrusted apps, on userdebug or eng builds only. (Temporarily at
least.)
Bug: 193603140
Test: Manual - odsign successfully runs the VM at boot when needed.
