41ab3a9cfe net/udp_input: Only dup packets for broadcast / multicast. 
We found previous multicast support (https://github.com/apache/nuttx/pull/12015) harms some unicast situation, and the `udp_input` should not dup packets for unicast.
Now, we only pass broadcast / multicast packets into each listener and let the code under control of `CONFIG_NET_BROADCAST`.

f3b34c84c2 net/nat: Support IPv6 Masquerading (NAT66) 
Notes:
1. This version of NAT66 is a stateful one like NAT44, corresponding to Linux's MASQUERADE target of ip6tables.  We can support stateless NAT66 & NPTv6 later by slightly modify the address & port selection logic (maybe just match the rules and skip the entry find).
2. We're using same flag `IFF_NAT` for both NAT44 & NAT66 to make control easier.  Which means, if we enable NAT, both NAT44 & NAT66 will be enabled.  If we don't want one of them, we can just disable that one in Kconfig.
3. Maybe we can accelerate the checksum adjustment by pre-calculate a difference of checksum, and apply it to each packet, instead of calling `net_chksum_adjust` each time.  Just a thought, maybe do it later.
4. IP fragment segments on NAT66 connections are not supported yet.

a1a09f271f net/nat: Support Symmetric NAT 
The symmetric NAT limits one external port to be used with only one peer ip:port.

Note:
1. To avoid using too much #ifdef, we're always passing peer_ip and peer_port as arguments, but won't use them under full cone NAT, let the compiler optimize them.
2. We need to find port binding without peer ip:port, so don't add peer ip:port into hash key.
3. Symmetric NAT needs to *select another external port if a port is used by any other NAT entry*, this behavior is exactly same as Full Cone NAT, so we don't need to change anything related to `ipv4_nat_port_inuse`.
