Summary

Deprecate `PresentationConnection.onstatechange` and implement explicit state transition events `onconnect`, `onclose`, `onterminate`. Implement `PresentationConnectionCloseEvent` for `onclose`. This allows us to expose a `PresentationConnectionCloseReason` for clients listening for `onclose`.
