devices: vvu: virtio-iommu support in virtio-vhost-user

Make vvu use devices use VFIO to manage their virt queues. This
alleviates the need to use noiommu mode. However, it is still necessary
to use `vfio_iommu_type1.allow_unsafe_interrupts=1`.

BUG=b:202151642,b:215310597
TEST=launch sibling with vvu + virtio-iommu

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
