Also, in EventStateManager, convert `ComputeScrollTarget()` and `ComputeScrollTargetAndMayAdjustWheelEvent()` to return `ScrollContainerFrame*` so that we can drop more unnecessarily `do_QueryFrame`. Due to removing `nsIScrollableFrame` forward declaration in DOM headers, we have to add `nsIScrollableFrame` forward declaration temporarily in nsMenuPopupFrame.h to make this patch compile, but we'll remove it once we remove `nsIScrollableFrame` under layout/.
