doc: clarify deprecation status for flow actions PF and VF

Browse Source 
These actions have been deprecated since DPDK 21.11 as
ambiguous and hard-to-use, but their removal might not
be popular because net drivers i40e, ixgbe and txgbe
employ these actions in complicated "PF/VF + QUEUE"
tunnel rule support. Maintainers of these drivers
should voice their attitude to the said problem.

For now, document the status in deprecation notes.

Also compile time flag ``RTE_ETHDEV_QUEUE_STAT_CNTRS`` will be removed.
* ethdev: Items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID`` are
deprecated as hard-to-use / ambiguous and will be removed in DPDK 22.11.
* ethdev: Flow actions ``PF`` and ``VF`` have been deprecated since DPDK 21.11
and are yet to be removed. That still has not happened because there are net
drivers which support combined use of either action ``PF`` or action ``VF``
with action ``QUEUE``, namely, i40e, ixgbe and txgbe (L2 tunnel rule).
It is unclear whether it is acceptable to just drop support for
such a complex use case, so maintainers of the said drivers
should take a closer look at this and provide assistance.
