Bug 1728246. Drop call to ComputeVisibility in nsDisplayList::Paint. r=mattwoodrow 

This will cause to paint items that would've previously been occlusion culled,
but we shouldn't be using this code in any performance critical areas and
removing the occlusion culling infrastructure will let us make the fast path
faster.
