Send Gameplay Event

This sends a dedicated Gameplay Event to the Ability Component.

Events can be used for many things such as triggering or interrupting abilities, notifying ongoing abilities about certain changes in the current context so they should react to it and so on.

Once this handler is invoked, it will create an Event Payload with meaningful information, that may be useful to any Gameplay Ability listening to this event.
