Process Hop-by-Hop header when forwarding IPv6 packets
Currently, we process IPv6 extension headers when receiving packets
but not when forwarding them. This is fine for the most part, with
with one exception: RFC 8200 requires that we process the
Hop-by-Hop headers even while forwarding packets.
This CL adds that support by invoking the Hop-by-hop logic performed
when receiving packets during forwarding as well.
