Compress arm64 GKI with lz4

Now that crosvm can use lz4-compressed kernel, this change compresses
microdroid kernels with lz4 to reduce bloating of virt apex.

* virt apex size becomes from 101MB to 84MB.
* MicrodroidBenchmarks shows that there is no performance regression.

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.
