Check view drawing order in ViewGroup#getChildLocalHitRegion

Before this change, ViewGroup#getChildLocalHitRegion will clip a view's
hit region when its slibing view is reciving MotionEvents despite of the
view order.
This doesn't work when two views overlaps and the bottom view is handling
MotionEvents. Because the top view's hit region will get clipped by the
bottom view's bounds.
This CL adds the view order check and fixed the issue.
