[EXT] [PATCH v2 01/14] cryptodev: redefine ec group enum

[Akhil Goyal]

> - EC enum was renamed to rte_crypto_curve_id.
> Elliptic curve enum name was incorrectly associated
> with group (it comes from current tls registry name).
> - Clarified comments about TLS deprecation.
> Some curves included are deprecated with TLS 1.3.
> Comments to address it were added.
> - Clarified FFDH groups usage.
> Elliptic curves IDs in TLS are placed in the same registry
> as FFDH. Cryptodev does not assign specific groups, and
> if specific groups would be assigned by DPDK, it cannot be
> TLS SupportedGroups registry, as it would conflict with
> other protocols like IPSec.
> - Added IANA reference.
> Only few selected curves are included in previously
> referenced rfc8422. IANA reference is added instead.
> - Removed UNKNOWN ec group.
> There is no default value, and there is no UNKNOWN
> elliptic curve.
