Life would be too simple if we could just call osinfo_os_get_all_devices()
for determining virtio-1.0 support for Windows guests. Now that we've
extracted the libosinfo logic that identifies the "best" virtio driver
(for copying its files into the guest), fetch the list of devices
supported by the same "best driver" as well. Use that list, in addition to
the one from osinfo_os_get_all_devices(), for determining (Q35 and)
virtio-1.0 support.
Thankfully this mess is not needed when converting Linux guests.
With this, we need to revert the data for three Windows-based test cases
to their pre-f0cea012d018 status (modulo intermediary commits 4f6b143c1cb3
("output: -o libvirt, qemu: Use correct device name for vsock",
2022-01-20) and 4c3d0b8b3b4b ("output: -o libvirt: Fix <graphics/> element
port/autoport", 2022-01-20)).
