Vulkan: Fix pipeline stage when waiting on a semaphore Using VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT in pWaitDstStageMask doesn't create a dependency, since no memory is accessed during that stage. Switch to VK_PIPELINE_STAGE_ALL_COMMANDS_BIT to synchronize all accesses. This fixes flickering observed in WebGL on ARM GPUs when composited using Vulkan in Chromium.
