Fixes ENYO-510, BHV-17852

## Issue
When scrolling without animation, `updatePagingControlState` wasn't being called because it was only called during bounds setup and in response to ScrollMath.onScroll. Actions like `scrollTo` or 5-waying to a control in a list would therefore not correctly update the paging controls.

## Fix
Move paging control state check into effectScroll where all scroll actions bottleneck.
