virtio,pci,pc: features, fixes

users can now control VM bit in smbios.
vhost-user-device is now user-createable.
intel_iommu now supports PRI
virtio-net now supports GSO over UDP tunnel
ghes now supports error injection
amd iommu now supports dma remapping for vfio
better error messages for virtio

small fixes all over the place.
