[iOS] Reintroduce adaptive deceleration tracking for scroll views behind an
off-by-default feature flag
https://bugs.webkit.org/show_bug.cgi?id=309928
rdar://172521017
Reviewed by Wenson Hsieh and Lily Spiniolas.
There are some kinks with the behavior change in 305618@main, as we've
seen with the revert in webkit.org/b/306977. This patch brings back said
behavior change but gates it behind an off-by-default feature flag. This
will help local testing of the _setDecelerationTrackingBehavior: SPI.
