Matthew HodgsonandClaude Fable 5 c464be40ac Implement MSC4233: remember which server a user knocked through ...

Fixes rescinding and denying knocks over federation (#18030):

- Remember the server that fulfilled our /send_knock in a new
  local_knock_via_servers table.
- Route a rescission of the knock (make_leave/send_leave) through that
  server, instead of only rescinding locally.
- Send a leave/ban denying a knock to the knocking user's server (the
  same mechanism as invite rescissions), and accept such an event as an
  out-of-band retraction on the knocking server when it references the
  knock in its auth events and comes from the server we knocked
  through (or the denying user's own server).

Gated behind the experimental msc4233_enabled flag.
