[v4,0/8] Introduce CPU crypto mode

  Originally both SW and HW crypto PMDs use rte_crypot_op based API to
process the crypto workload asynchronously. This way provides uniformity
to both PMD types, but also introduce unnecessary performance penalty to
SW PMDs that have to "simulate" HW async behavior (crypto-ops
enqueue/dequeue, HW addresses computations, storing/dereferencing user
provided data (mbuf) for each crypto-op, etc).

The aim is to introduce a new optional API for SW crypto-devices
to perform crypto processing in a synchronous manner.

v3 to v4 changes:
 - add feature discovery in the ipsec example application when
   using cpu-crypto
 - add gmac in aesni-gcm
 - add tests for aesni-gcm/cpu crypto mode
 - add documentation: pg and rel notes
 - remove xform flags as no longer needed
 - add some extra API comments
 - remove compilation error from v3
