scroll-snap doesn't respect |enable_scroll_animator| preference

Project Member Reported by bokan@chromium.org, Dec 18 
Chrome Version       : 72.0.3626.14
OS Version: All
URLs (if applicable) : https://snap.glitch.me/carousel.html

What steps will reproduce the problem?
1. Launch Chrome with --disable-smooth-scrolling

What is the expected result?
Releasing the scroller on a non-snap location should immediately snap. 

What happens instead of that?
The scroller smoothly animates to the snap location

This flag is used by system-wide settings to disable animations so we should respect it for scroll snapping as well.

David, I am looking into this issue right now and noticed that the programmatic scrolls don't respect |enable_scroll_animator| either. Should we respect the preference for all the programmatic scrolls as well, or should we just fix for the snap scrolls?

Yes, I think if scroll_animator is disabled then we should never do smooth scrolls, so we should respect the preference for all programmatic scrolls.
