Previously for the table of contents A/B test we triggered
scroll events when the table of contents was scrolled into
view. Now this is never referenced, so the code is cleaned
up to only apply to when the title is scrolled into view.

Move A/B test code to AB.js
Consolidate the show/hide code spread across scrollObserver
and stickyHeader by adding a show and hide function.
This is needed to fix T296680
Change-Id: Ia2e0c50278df0dfc1600610f281be20f4cc755c2
- Permits logging for scroll events without sticky header.
- Update function name to be more precise.

- Pull IntersectionObserver into new file to share observer with different callbacks:
- Wrap show/hide functionality of sticky header in conditionals based on user test group or by default.
- Fire hooks for scroll event tracking in WME.
- Add new js for A/B test functions and variables:
- Fire hook to send data for A/B test initialization.
- Update main js to include scrollObserver, A/B test init functionality.
- Add A/B test config.
- Update ResourceLoader package dependencies for sticky header.
- Though not a strict dependency, see I42e3e7c2084c1e88363d5d1662630ed23a28c4d2 in WME repo which uses these hooks to log scroll events.
- This patch includes changes from I56f40e706f8706fde1c0891a0561dd32c5e02bfc which were consolidated here for simplicity and ease of review - related to T292587 which calls for logging an init event for bucketing of users during A/B testing.
