Haiyue Wang efc1b2799f net/ice: optimize protocol extraction by dynamic mbuf 
The original design is to use rte_mbuf::udata64 to save the metadata of
protocol extraction which has network protocol data fields and type, a
private API is used to decode this metadata.

Use the dynamic mbuf field and flags to register the needed fields in
mbuf, to avoid overwriting 'rte_mbuf::udata64', since the application
may use it. Now the protocol extraction metadate is saved into dynamic
mbuf field with 4B size, and its type and validity is indicated by the
related dynamic mbuf flags in 'rte_mbuf::ol_flags'.
