virtio,pc,pci: features, fixes, cleanups

Features:

SR-IOV emulation for pci
virtio-mem-pci support for s390
interleave support for cxl
big endian support for vdpa svq
new QAPI events for vhost-user

Also vIOMMU reset order fixups are in.
Fixes, cleanups all over the place.

the 'exit' phase and this sequencing makes sure no outstanding DMA request
