virtio,pc,pci: fixes, features, cleanups

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.
