vmbase: Introduce compat_android_13 feature

Put the workarounds for Android 13 recently added to vmbase (previously
in libhyp) behind a Rust crate feature to ensure that the "proper"
implementation gets compiled (then optimized out), more clearly document
that particular code, and provide a single point for "flipping the
switch" when the support gets removed (possibly progressively, by using
Android Trunk Stable flags).

Test: m libvmbase # with the feature set and unset in Android.bp

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.
