i just had all the interactive verif reqs reappear on syncing a client for the first time in a few months. what's more, i couldn't reliably cancel them (either due to the X button not working, or the app being so overloaded it didn't respond to clicks

I suspect this is the same cause as #8629

Trivial reproduction steps:

  1. Close Bob's client
  2. Have Alice start a verification
  3. Have Alice cancel that verification
  4. Start Bob's client

Bob then receives an unexpected verification request, and a silenced error about an unhandled m.key.verification.cancel event.

Fixes element-hq/element-web#9197
Fixes element-hq/element-web#8629

The issue is partially fixed by matrix-org/matrix-react-sdk#3123 in that users would no longer see "Incoming request", but would launch their client to a bunch of "key verification cancelled" dialogs. To work around this, we just don't handle key verification requests which we know are cancelled.

The changes are a bit awkward (flagging the event as cancelled instead of filtering it) because:
* We probably don't want to prevent events getting sent over the EventEmitter because applications may still rely on them.
* The cypto side only has visibility of 1 event at a time, so it needs to have some kind of flag to rely on.

An attempt has been made to generalize the new event flag for possible future cases.
