This PR adds a new `EventDispatcherInterface` in `Contracts`. This interface contains only one method: `dispatch($event, $eventName)`. That covers almost all use cases of the event dispatcher in components (some use add/removeListeners/Subscribers but they are a minority.)
While doing so, it allows dispatching any objects as events - not only instances of `Event`.
This allows decoupling e.g. `Messenger` from the `EventDispatcher` component.
Next steps could be about planning to remove the base `Event` class from some concrete event classes and/or moving `EventSubscriberInterface` to `symfony/contracts`. It would allow decoupling e.g. `Workflow` from the component - but that's too far away for now, let's think about it in 5.1.
