examples/ipsec-secgw: support poll mode NEON LPM lookup

This adds the support of NEON based LPM lookup along with
multi packet processing for burst send in packets routing.

Performance impact:
On cn10k, with poll mode inline protocol, outbound performance
increased by ~8% and inbound performance increased by ~6%.
