ethdev: add IPv6 FL and TC field identifiers

Add new "rte_flow_field_id" enumeration values to describe both IPv6
traffic class and IPv6 flow label fields.

The TC value is "RTE_FLOW_FIELD_IPV6_TRAFFIC_CLASS" in flow API and
"ipv6_traffic_class" in testpmd command.
The FL value is "RTE_FLOW_FIELD_IPV6_FLOW_LABEL" in flow API and
"ipv6_flow_label" in testpmd command.
