From: Satha Rao <skotesh...@marvell.com>

Existing Rx desc used count command extended to get Tx queue
used count.
    testpmd> show port 0 rxq 0 desc used count
    testpmd> show port 0 txq 0 desc used count

Signed-off-by: Satha Rao <skotesh...@marvell.com>

Depends-on: series-30833 ("ethdev: support Tx queue used count")

v2:
 extended rx_queue_desc_used_count command to support Tx
 updated testpmd_app_ug with new command
