This PR moves around some parts and refactors the event responder system to cater for event responders having new lifecycle events (to be added in a follow up PR). The big difference is that handleEvent -> onEvent and it now has another argument, event.

I had feedback that it was confusing why the context object had so many concerns, so that's been taken care of now – it only deals with the context of the responder dealing with events, the actual event properties are in the event object.

I've also cleaned up and removed all the prototype methods and instead opted for static methods and using closures.

Ref #15257
