feat(client): try restricted proxy if NAT unknown

Just once, to offload unrestricted proxies.
This is useful when our STUN servers are blocked or don't support
the NAT discovery feature, or if they're just slow.

Closes https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40271 .
Supersedes https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/merge_requests/417 .
This simplifies the code and (probably) removes the need for
`StripLocalAddresses`, although makes us more dependent on Pion.
