script: Fire scroll event whenever JS scrolled (#38321)

Browse source 
Implement JS scroll event firing compliant to
https://drafts.csswg.org/cssom-view/#scrolling-events. Basically
whenever, the an element or the viewport is scrolled, we will fire a
scroll event. The changes push a scroll event whenever an API causes a
scroll position to change.

Testing: New WPT tests for basic APIs.
