Move FETCH to a bidi stream as part of draft-18 update.

Remove request_id from FETCH_OK and REQUEST_ERROR so that callback data structures are aligned with wire messages. FIN always follows REQUEST_ERROR. As the messages and external API structs are now the same, this deletes a lot of code, unfortunately with a bigger blast radius than hoped.

FetchResponseCallback is no longer handled in the FetchTask at all.

Not in production.
