api: pktio: add pktio capability for skip offset support
Current odp_pktio_skip_set() is supposed to work on all
platforms. Since this API is HW dependent as it asks ingress
parser to skip X bytes before starting to parse packet for standard
L2/L3 protocols, it may not be supported by every platforms.
Hence adding a set_op capability in packet_io for reporting
if a given platform supports it or not.
