Similar to IPIP and IP6I6 tunnels, introduce sw acceleration for IPv4 over
IPv6 and SIT tunnels in the netfilter flowtable infrastructure.

Changes in v2:
- Fix MTU check in nf_flow_offload_forward() and in
nf_flow_offload_ipv6_forward()
- Add SIT sw acceleration support
- Link to v1: https://lore.kernel.org/r/20260505-b4-flowtable-sw-accel-...
