Provides a forward-compatibility layer for the Symfony 5 event class.

Symfony 5 relies on the Symfony\Contracts\EventDispatcher\Event class. In order to prepare for updates, code that wishes to extend Symfony's Event class should extend this intermediary class, which will handle switching from Symfony\Component to Symfony\Contracts without a further change.
