vfio: Introduce a new header file for VFIOIOMMUFD declarations

Gather all VFIOIOMMUFD related declarations introduced by commits
5ee3dc7af785 ("vfio/iommufd: Implement the iommufd backend") and
5b1e96e65403 ("vfio/iommufd: Introduce auto domain creation") into
"vfio-iommufd.h". This to reduce exposure of VFIO internals in
"hw/vfio/vfio-common.h".
