Missing "scroll into view" Actions primitive

[shs96c]

Mid-way through executing a sequence of actions it's useful to be able to scroll an element into view. A "scroll into view" primitive would enable this.

Is this meant to target level 2? It seems more like an omission from the actions API than scope creep to me.

Yeah, it's level 2. @jgraham and I discussed this on the IRC channel a few months ago. Adding it requires us to add new functionality, and that's something we're not meant to do in the CR period.

IMO, we should follow what CSSOM View does here and offer all three of scrollIntoView, scrollTo, and scrollBy on elements.

Something semantically equivalent would be good. There is definitely a difference between scrolling an element into view, and scrolling a page by a certain amount. Reading CSSOM, it looks like `scrollTo` and `scrollBy` both end up delegating to `scroll`.

Element.prototype.scroll is identical to Element.prototype.scrollTo; both Element.prototype.scrollBy and Element.prototype.scrollTo call an internal function that does the actual scrolling.
