Add missing vnic-type choices to --vnic-type

The --vnic-type choices list was missing several vnic types that
exist in neutron-lib's VNIC_TYPES: accelerator-direct (added in
Xena for smartNIC SR-IOV), accelerator-direct-physical, and
smart-nic. This forced users to use curl to create ports with
these vnic types.

Add all missing types to the choices tuple and help text so the
CLI matches neutron-lib.
