libhypervisor_backends: add basic x86 support

Make the hypervisor_backends library available for x86 with the basic
support:
- Determine the hypervisor type based on cpuid and distinguish if
  running Protected or Regular VMs based on it.
- Add support for page sharing which is required for
  ProtectedKvmHypervisor case.

Test: Successfully use libhypervisor_backends in Trusty for x86_64.
      Run: `m libhypervisor_backends` for x86_64 target.

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.
