bug: Top level Input Event Handling cannot be stopped from bubbling

[eonarheim]

Bug, we should be able to .cancel() and an event and have it stop bubbling at the top most pointer event handler

Discussed in #3249

Hello! I've been trying out excalibur.js a little over last few days, but hit a problem with event handlers I couldn't figure out using the docs and github issues.

I implemented drag&drop panning in the scene (think grand strategy game), using https://excaliburjs.com/docs/pointers/#event-handlers. In that scene I render an actor that has a click handler pointerdown like this: https://excaliburjs.com/docs/pointers#handling-pointer-events-on-actors. However, there is no way to stop that event from bubbling up to the scene, so the event handler for drag&drop panning also always fires. I tried evt.nativeEvent.stopPropagation() etc., but it didn't change anything.

Thanks!
