Improve hook to register events on canvas

[axelboc]

I'm rethinking useCanvasEvents a bit. The hook is now called useCanvasEvent (singular) and allows registering only one event listener at a time. This brings the API closer to that of useEventListener from react-hookz and avoids registering event listeners that are not actually used.

Additional benefits of the new implementation:

• It allows more events to be registered, not just pointerdown, pointerup, pointermove and wheel — so basically any event that has offsetX and offsetY (i.e. any event that extends MouseEvent, including WheelEvent, PointerEvent, DragEvent).
• It uses useSyncedRef so consumers don't have to wrap their listeners in useCallback — this simplifies a bunch of code.
• It allows overriding the options passed to addEventListener, notably passive, which might be useful at some point notably for wheel events (currently, the only place where we do need to configure passive is in useWheelCapture but it doesn't rely on useCanvasEvent).

So much cleaner from the consumer perspective. Well done 👍
