fix: add timeout for incoming connections and build-in protocols (#1292)

Ensure that we don't wait forever for upgrading an inbound connection

Note that transports should return an AbortableSource when passed an
AbortSignal so outbound connections to not need the same fix.

Also adds default timeouts for the ping, fetch, and identify protocols.
