[v1 06/12] net/enetc: Add packet type parsing support

[vanshika.shukla@nxp.com]

From: Vanshika Shukla <vanshika.shukla@nxp.com>

Introduces packet type parsing for ENETC4 PMD, supporting:

- RTE_PTYPE_L2_ETHER (Ethernet II)
- RTE_PTYPE_L3_IPV4 (IPv4)
- RTE_PTYPE_L3_IPV6 (IPv6)
- RTE_PTYPE_L4_TCP (TCP)
- RTE_PTYPE_L4_UDP (UDP)
- RTE_PTYPE_L4_SCTP (SCTP)
- RTE_PTYPE_L4_ICMP (ICMP)
- RTE_PTYPE_L4_FRAG (IPv4/IPv6 fragmentation)
- RTE_PTYPE_TUNNEL_ESP (ESP tunneling)
