This change gives a new type (dalvik_dynamic_config_prop) to some ART
properties such as dalvik.vm.dex2oat-cpu-set and adds a new rule to
allow system server to set them.
Bug: 274530433
Test: Locally added some code to set those properties and saw it being
successfull.

We want to allow both the VM and ART to contribute to the VM config
(e.g. memory size), so define labels for 2 sets of properties and
grant the necessary access.

If the directory is non-empty when we start we need to delete
everything in it, but didn't have enough access:
avc: denied { getattr } for
path="/data/misc/apexdata/com.android.art/staging/boot-framework.art"
dev="dm-37" ino=57755 scontext=u:r:composd:s0

We need to remove any existing files (and the directory) to allow
odrefresh in the VM to re-create them via authfs.
But we don't need, and shouldn't have, any other access to them.

Besides the basic execution that is similar to the (deprecating)
odrefresh case, fd_server also needs to be able to create and change
files in the output directory.

composd in responsible to prepare the staging directory for odrefresh
(in the VM) to write the output to. Temporary output should be put in a
staged directory with a temporary apex_art_staging_data_file context.
When a compilation is finished, the files can then be moved to the final
directory with the final context.

Only ro.zygote is currently used, though we'll need to a few others of
the same property context.

They are served by the same process but have different clients:
- the main interface is exposed to system server;
- the internal interface is called by odrefresh when spawned by composd.

Also allow composd to kill odrefresh (it execs it); this is necessary
for cancel() to work.

Also allow odrefresh to run pvm_exec to talk to the CompOS VM.
And I moved the dontaudit & neverallow rules to the bottom while I was here.

Add what we need to allow composd to run and expose an AIDL service.
Also delete the policy for compsvc; we never access it in the host
now, and the real policy is in microdroid. Retain the compos_exec
type, since it is referenced in the APEX sepolicy.
