Auto merge of #27164 - jdm:tungstenite, r=nox

Replace ws-rs with async-tungstenite.

This change moves us from ws-rs (which doesn't see a lot of maintainer activity) and its custom async implementation to tungstenite and the tokio ecosystem. This is particularly important because of #27043, which breaks SSL websockets on Windows.

Depends on https://github.com/sdroege/async-tungstenite/pull/40/.
