Add support to macOS Virtualization Framework

[laozc]

This PR allows vagrant-libvirt to work with brew installed libvirt/QEMU with user networking.
Verified on Apple M2.

Vagrant.configure("2") do |config|
  config.vm.box = "ppggff/centos-7-aarch64-2009-4K"

  config.vm.provider "libvirt" do |virt|
    virt.driver = 'hvf'
    virt.loader = '/opt/homebrew/share/qemu/edk2-aarch64-code.fd'
    virt.nvram_template = '/opt/homebrew/share/qemu/edk2-arm-vars.fd'
    virt.nvram = "#{Dir.home}/works/libvirt-arm/edk2-arm-vars.fd"
    virt.uri = "qemu:///session"
    virt.system_uri = "qemu:///session"
    virt.socket = "#{Dir.home}/.cache/libvirt/libvirt-sock"
    # virt.qemu_user_networking = true
    # virt.cpu_mode = 'custom'
    # virt.cpu_match = 'exact'
    # virt.cpu_fallback = 'forbid'
    # virt.cpu_model = 'host'
  end

  config.vm.synced_folder ".", "/vagrant", disabled: false
end

Fixes: #1205

One query and I'm also wondering if you think it's reasonable to default the qemu URIs based on the host OS as well?

Also does user networking have other interpretations? https://wiki.qemu.org/Documentation/Networking suggests it's understood to mean something different to the host port forwarding. If there is a canonical resource referring to this approach as user networking will want to make sure referencing it in the docs.

Btw, thanks so much, it's great to have something here that will allow MacOS users to be able to use this project.

I'm looking at this on a phone, so I could be missing something, if there can't be any networks for qemu_user_networking seems like could just return an empty list here and the rest of the function doesn't need to be modified at all?

[laozc]

You're correct. Just made the change to return an empty list instead.

The current macOS brew package doesn't seem to offer qemu:///system like Linux.
I believe it would be great to set the default QEMU URI to minimize the user config.

It is the same thing as mentioned in the wiki page.

Sure. It's great to unblock people who experienced the same issue as I did. :)

Please be aware that the current latest libvirt version 9.6.0 has some issue on M1 Mac which prevents the volume from being created.
https://gitlab.com/libvirt/libvirt/-/issues/518

You may use libvirt 9.5.0.
