    conf: Introduce igb model for <interface>
    
    igb is a new network device which will be introduced with QEMU 8.0.0.
    It is a successor of e1000e so it has PCIe interface and is understands
    virtio-net headers as e1000e does.

More patches for the qemu capability and docs.
Michal, I found that this device is also supported in other ARCHes like s390x, ppc64, aarch64, riscv64...
Please help to update the qemu capability replies and tests for these ARCHes.

As discussed on the list, libvirt deliberately does not have capabilities check for NIC models.
