Since authz* objects are supported since qemu 4.0(around fb5c4ebc08) so the in first patch the
qemu capability flag of authz objects to check if the target qemu support this feature. And add tests for that
capability.

I disagree the authz* are set as domain device because the authz* are objects in qemu:
-object authz-simple,id=id,identity=string
While for the devices in libvirt, they usually look like as the following in qemu cmdline:
-device NAME,...
