[VirtMgr] Allow host-controlled avf/untrusted prop

Allow addition of properties at /avf/untrusted in the DT overlay
created by virtmgr. While I'm here, refactor reference_dt into
dt_overlay to allow this & remove confusion of reference DT which from
the pt. of view of pVM is expected from ABL.

Include (a hardcoded) instance_id of VM in the DT overlay!

Test: vm_shell start-microdroid --auto-connect
Test: Check /proc/device-tree/avf/untrusted/instance-id has value of hardcoded id in non-protected VM
Test: atest virtualizationmanager_device_test

Android Virtualization Framework (AVF)

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.

Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.

If you want a quick start, see the getting started guideline and follow the steps there.
