Reland of DevTools: properly restore selected DOMNode in Elements panel.

Reland of DevTools: properly restore selected DOMNode in Elements panel.

This patch is a reland of https://crrev.com/2428823002/, merged with
https://crrev.com/2448963003.

Since the http://crrev.com/b4d6bf98e, we started
sending two "documentUpdated" events for every
page reload.

It's not a bad thing by itself (but probably needs
addressing in a follow-up), but the element restoration
logic is unprepared for this.

This patch re-writes the element restoring logic in the
elements panel so that we will try to restore to the last
focused selected element.
