doc: announce changes in bbdev related to enum extension

Browse Source 
Intent to resolve in DPDK 22.11 historical usage which prevents
graceful extension of enum and API without troublesome ABI breakage
as well as extending API RTE_BBDEV_OP_FFT for new operation type
in bbdev as well as other new members in existing structures.

alternative is implemented.
The legacy actions should be removed in DPDK 22.11.
* bbdev: ``RTE_BBDEV_OP_TYPE_COUNT`` terminating the ``rte_bbdev_op_type``
enum will be deprecated and instead use fixed array size when required
to allow for future enum extension.
Will extend API to support new operation type ``RTE_BBDEV_OP_FFT`` as per
this `RFC <https://patches.dpdk.org/project/dpdk/list/?series=22111>`__.
New members will be added in ``rte_bbdev_driver_info`` to expose
PMD queue topology inspired by
this `RFC <https://patches.dpdk.org/project/dpdk/list/?series=22076>`__.
New member will be added in ``rte_bbdev_driver_info`` to expose
the device status as per
this `RFC <https://patches.dpdk.org/project/dpdk/list/?series=23367>`__.
This should be updated in DPDK 22.11.
* cryptodev: Hide structures ``rte_cryptodev_sym_session`` and
``rte_cryptodev_asym_session`` to remove unnecessary indirection between
session and the private data of session. An opaque pointer can be exposed
