Implement time-based memory balloon inflation

This change implements time-based memory balloon inflation for
FerroChrome, gradually increasing memory reclamation while the
application is stopped.

On application stop, the memory balloon is inflated to an initial 10% of
total memory. It then incrementally inflates by an additional 5% every
60 seconds, up to a maximum of 50%. When the application starts, the
balloon is deflated to 0%, and the time-based balloon inflation task is
cancelled.

Bug: b/400590341
Test: Verify Vm inflate balloon by 5% every 60 seconds when App is in
background. The balloon size stops inflating after reaching 50%.

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.
