Vulkan: Remove flush semaphore chain This avoids using an unbounded number of semaphores in between calls to swapbuffers. Using two semaphores should be sufficient to synchronize swaps. In addition, fix tracking of VkPipelineStageFlags by creating a 2nd vector parallel to the semaphores vector. The last fix assumed there could only be 2 wait semaphores, but that bound only applied to signal semaphores. After this change, there can only be one signal semaphore, but there's still no bound to wait semaphores.
