[pointerevents] Should WheelEvent definitions move to PointerEvent? (#557)

mustaqahmed has just created a new issue for https://github.com/w3c/pointerevents:

== Should WheelEvent definitions move to PointerEvent? ==
Both [Mouse Events](https://w3c.github.io/uievents/#events-mouseevents) and [Wheel Events](https://w3c.github.io/uievents/#events-wheelevents) are currently defined in the UI Events spec.  During TPAC 2024, we agreed to migrate MouseEvent definitions from there to the Pointer Events spec (see WebAppsWG [Day 3](https://docs.google.com/document/d/1EtEFfQ3sJ6lECF3ojmbLKIH7iKN4RdGrapVosQB-wqI/edit?tab=t.0#heading=h.rhzrl9xe8dq8) notes on "topic: ui events").

Should we do the same with WheelEvent definitions?

One possible first step seems to be making WheelEvent a subclass of PointerEvent, from being a [subclass of MouseEvent](https://w3c.github.io/uievents/#interface-wheelevent).  Could this be a compat concern?
