ice: Add more FDIR filter type for AVF

FDIR for AVF can forward
- L2TPV3 packets by matching session id.
- IPSEC ESP packets by matching security parameter index.
- IPSEC AH packets by matching security parameter index.
- NAT_T ESP packets by matching security parameter index.
- Any PFCP session packets(s field is 1).
