  [Pointer Events] Add a stub implementation for the `getCoalescedEvents` function of the PointerEvent interface
https://bugs.webkit.org/show_bug.cgi?id=276832
rdar://132105605

Reviewed by Tim Nguyen.

Add a stub implementation for the `getCoalescedEvents` function of the `PointerEvent` interface,
as per the corresponding UI events specification (https://w3c.github.io/pointerevents/#dom-pointerevent-getcoalescedevents).

Also slightly refactor the `PointerEvent` constructors to allow for explicitly setting the value of
`bubbles` and `isCancelable`, which must be set to `false` for the coalesced events.

Also adds a runtime feature flag to control its enablement.
