* More slow test fixes * Create a new event type for verification requests Previous PRs (https://github.com/matrix-org/matrix-js-sdk/pull/3449, etc) have pulled out an interface from the `VerificationRequest` class, but applications registering for the `CryptoEvent.VerificationRequest` event could still be expecting a fully-fledged class rather than the interface. To handle this without breaking backwards compat, add a new event type that carries the interface, not the class.
