raw/ioat: add separate API for fence call
Rather than having the fence signalled via a flag on a descriptor - which
requires reading the docs to find out whether the flag needs to go on the
last descriptor before, or the first descriptor after the fence - we can
instead add a separate fence API call. This becomes unambiguous to use,
since the fence call explicitly comes between two other enqueue calls. It
also allows more freedom of implementation in the driver code.

vhost: remove dequeue zero-copy support
Dequeue zero-copy removal was announced in DPDK v20.08.
This feature brings constraints which makes the maintenance
of the Vhost library difficult. Its limitations makes it also
difficult to use by the applications (Tx vring starvation).
Removing it makes it easier to add new features, and also remove
some code in the hot path, which should bring a performance
improvement for the standard path.
