When flushing the render target cache for future operations, we need a stall at pixel scoreboard. We likely didn't see any issue until now because a change in render target added the pb-stall. When using a 2 compute shaders with the following pattern : vkCmdDispatch() vkCmdPipelineBarrier() ImageBarrier with (src|dst)AccessMask=0 & identical layout vkCmdDispatch() we should ensure that the first dispatch is completed before executing the second one, otherwise they can race to on resource accesses. This fixes failures in some new CTS tests.
