Add new IOMMU modes for using iommufd in compatibility mode with VFIO_TYPE1_IOMMU and VFIO_TYPE1v2_IOMMU.
In these modes, VFIO selftests will open /dev/iommu and treats it as a container FD (as if it had opened /dev/vfio/vfio) and the kernel translates the container ioctls to iommufd calls transparently.
