VM payload require an api to allow storing n bytes' data with
confidentialty & tamper evidence integrity guarantees.

Microdroid Manager implements this using the vm_secret module, which
uses the payload's DICE chain to store/get secret from Secretkeeper.

Additionally introduce a test that uses these api.
Test: #rollbackProtectedDataOfPayload

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.
