    ethdev: add Tx queue used count query

    Introduce a new API to retrieve the number of used descriptors
    in a Tx queue. Applications can leverage this API in the fast path to
    inspect the Tx queue occupancy and take appropriate actions based on the
    available free descriptors.

    A notable use case could be implementing Random Early Discard (RED)
    in software based on Tx queue occupancy.
