virtio,pci,pc: features,fixes

pci: Initial support for SPDM Responders
cxl: Add support for scan media, feature commands, device patrol scrub
    control, DDR5 ECS control, firmware updates
virtio: in-order support
virtio-net: support for SR-IOV emulation (note: known issues on s390,
                                          might get reverted if not fixed)
smbios: memory device size is now configurable per Machine
cpu: architecture agnostic code to support vCPU Hotplug

Fixes, cleanups all over the place.
