[wptrunner] Optimize server test order

TestEnvironment.ensure_started() synchronously polls that all servers are started. The non-webtransport-h3 servers are often tested first and immediately fail with "Connection refused", which puts them in the pending list. This spins the polling loop at least once and delays startup by at least 0.5s.

Run the webtransport-h3 server test first, which blocks. This provides additional time for the non-webtransport-h3 servers to become ready, which means the TestEnvironment often only needs to poll once.

This speeds up ensure_started() from ~2.2s -> ~1.7s and improves wptrunner's interactive UX (https://crbug.com/339299999). No functional change.
