Remove common EventConverterOzone class & move to EventConverterEvdev

There's no need for this interface in common code; the DispatchEvent
function can be moved onto EventFactoryOzone.

We're still relying on this class in the evdev implementation for

- unifying storage of TouchEventConverter & KeyEventConverter instances
- overriding event dispatching in the tests

Therefore, move it into evdev as EventConverterEvdev.
