common/iavf: support eCPRI protocol header fields

Add eCPRI header and its field selectors, including MSG_TYPE, PCID
and RTCID. Since the offset of PCID is same as RTCID, we just add one
MACRO for these two fields. For MSG Type 0, ecpriRtcid/ecpriPcid field
within the eCPRI header will be extracted to Field Vector for FDIR and
RSS.

SPEC for eCPRI:
