fix(ext/websocket): Ensure that errors are available after async response returns (#19642)

Fixes the WPT tests that test w/invalid codes. Also explicitly ignoring
some h2 tests to hopefully prevent flakes.

The previous changes to WebSocketStream introduced a bug where the close
errors were not made available if the `pull` method was re-entrant.
