revdial/v2: add new simpler, non-multiplexing revdial implementation

The old revdial has a simple multiplexing protocol that was like
HTTP/2 but without flow control, etc. But it was too simple (no flow
control) and too complex. Instead, just use one TCP connection per
reverse dialed connection. For now, the NAT'ed machine needs to go
re-connect for each incoming connection, but in practice that's just
once.

The old implementation is retained for now until all the buildlets are
updated.

Updates golang/go#31639
