[libvirt] [PATCHv2 02/16] conf: Add hvf domain type

[Roman Bolshakov]

QEMU supports Hypervisor.framework since 2.12 as hvf accel.
Hypervisor.framework provides a lightweight interface to run a virtual
cpu on macOS without the need to install third-party kernel
extensions (KEXTs).

It's supported since macOS 10.10 on machines with Intel VT-x feature
set that includes Extended Page Tables (EPT) and Unrestricted Mode.
