Subject: [PATCH 01/10] p2p: fix marshaling of NAT in TOML (#31192)

This fixes an issue where a nat.Interface unmarshaled from the TOML
config file could not be re-marshaled to TOML correctly.

Fixes #31183

 (#31185)

We somehow forgot to add this in #30302, so discv5 and DNS have actually
been disabled since then.
