virtio,pc,pci: fixes, features, cleanups

Browse source 
asymmetric crypto support for cryptodev-vhost-user
 rom migration when rom size changes
 poison get, inject, clear; mock cxl events and irq support for cxl
 shadow virtqueue offload support for vhost-vdpa
 vdpa now maps shadow vrings with MAP_SHARED
 max_cpus went up to 1024 and we default to smbios 3.0 for pc
 
 Fixes, cleanups all over the place. In particular
     hw/acpi: Fix PM control register access
 works around a very long standing bug in memory core.
