cmd/stunstamp: refactor connection construction (#13110)
getConns() is now responsible for returning both stable and unstable
conns. conn and measureFn are now passed together via connAndMeasureFn.
newConnAndMeasureFn() is responsible for constructing them.

TCP measurement timeouts are adjusted to more closely match netcheck.

cmd/stunstamp: implement service to measure DERP STUN RTT (#12241)
stunstamp timestamping includes userspace and SO_TIMESTAMPING kernel
timestamping where available. Measurements are written locally to a
sqlite DB, exposed over an HTTP API, and written to prometheus
via remote-write protocol.
