In an eventdev world, multiple workers (with ordered queue) will be
working on IPsec ESP processing. The ESP header's sequence number is
unique and has to be sequentially incremented in an orderly manner.
This rises a need for incrementing sequence number in crypto stage
especially in event crypto adapter. By adding a user callback to
cryptodev at enqueue burst, the user callback will get executed
in the context of event crypto adapter. This helps the application
to increment the ESP sequence number atomically and orderly manner.

v3->v4:
    -Move callback init and cleanup under dev_configure
    -Update with memory ordering
    -Removed extra level of indirection
    -Add documentation

v2->v3:
    -Moved RCU under the cryptodev APIs
    -RCU is maintained per queue-pair
    -Changed name of few variables
    -Updated callback test with negative cases
    -Updated with required changes for meson

v1->v2:
    -Moved callback related members to the end of cryptodev struct
    -Added support for RCU
