vfio: Create host IOMMU device instance
Create host IOMMU device instance in vfio_attach_device() and call
.realize() to initialize it further.

Introuduce attribute VFIOIOMMUClass::hiod_typename and initialize
it based on VFIO backend type. It will facilitate HostIOMMUDevice
creation in vfio_attach_device().
