Vulkan: Fewer subgroup ops in seamful cubemap emulation Two values were retrieved from quad neighbors; layer and ma. The value of ma was retrieved as the helper invocations would otherwise have a different value as the major axis. This change makes the helpers rechoose ma based on the layer, which removes a number of subgroup operations. This is also more precise as the major axis value could be slightly different from the neighbor.
