Implement IntersectionObserver
https://bugs.webkit.org/show_bug.cgi?id=159475
Reviewed by Ryosuke Niwa.
Source/JavaScriptCore:
Add ENABLE_INTERSECTION_OBSERVER, enabled by default.

Source/WebCore:
Add bindings support for Intersection Observer
<https://wicg.github.io/IntersectionObserver/>
Code is wrapped in ENABLE(INTERSECTION_OBSERVER), and controlled by a runtime
Setting (off by default for now).
A minor bindings change was required to fix the callback code.
IntersectionObserver is just a shell for now.
