vmbase: Abstract CPU arch in write_volatile_u8()

Move write_volatile_u8() to the arch-agnostic import vmbase::arch, using
cfg_if to conditionally select the body of the function. Future
functions moved to this submodule will follow the same pattern, allowing
client code (including the rest of this crate) to become arch agnostic.

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.
