Re: [whatwg/dom] Which target could we expose in Event Timing? (#838)

**Which events**: https://wicg.github.io/event-timing/#sec-events-exposed. Note that we expose first-input (where the types are a subset of those) always, and slow events.

**How are they dispatched**: I don't understand this question. "They" = the events? I suspect the answer to that would be in the corresponding event's spec.

**How are they meant to be exposed**: similar to other performance entries, we have a PerformanceEventTiming object which is exposed on a size-bounded array on the performance timeline and exposed to a PerformanceObserver, both of which are exposed to Window. In terms of the timing, we expose once the information on the update the rendering step after event handlers have ran, so that we can expose the 'next paint' after those handlers have ran.
