Vulkan: Fix the VVL error for shaderRead to shaderRead barrier When we use image from fragment shader read to vertex shader read, we detect the case (same layout with only shader stage change) and just merge the barrier into one. But that can only done if these two usages are for the same render pass. If it is different render pass, then you still have to issue a new barrier. Previously there is no way to detect that the barrier was issued for which render pass. With the fix in crrev.com/cl/4136948, we now know which render pass issued the last barrier. With that we are able to limit the shader stage consolidation only if they are for the same render pass, thus fixing the VVL errors.
