Patch 10/14 net/cnxk: add MSNS inb SA and CN20K CPT result struct
----------------------------------------------------------------
Warning: undocumented API change in an installed header.
- ltype_mask, ltype_match, lid, noffset and offset are removed from
  struct rte_pmd_cnxk_rx_gen_inl_cfg in rte_pmd_cnxk.h.
- That struct is embedded in rte_pmd_cnxk_profile_cfg_params, used by
  rte_pmd_cnxk_nix_inl_custom_profile_setup() (experimental, 25.11).
- The removal is source-breaking and is not in the commit log.
Split it out and add a release note.

Warning: rte_pmd_cnxk_inl_inb_prof_sa_base_get() now returns the
default IPsec SA base when profile_id == UINT16_MAX. Neither the
Doxygen ("Custom profile ID to get the SA base for") nor the commit
log mention this.

Warning: a new typedef is added already marked @deprecated:
  typedef struct rte_pmd_cnxk_ipsec_inb_msns_sa
          rte_pmd_cnxk_ipsec_inb_sa_msns;
Drop it.

Info: RTE_PMD_CNXK_IPSEC_INB_MSNS_CTX_PUSH_SZ(x) is an identity macro,
and RTE_PMD_CNXK_IPSEC_INB_SA_MSNS_SZ_ALIGN duplicates
RTE_PMD_CNXK_IPSEC_INB_SA_MSNS_SZ.
