Correctly wait in the fragment stage until all semaphores are signaled
This fixes two issues:
- a crash if the application uses more than one semaphore for presenting because the driver expects one stage per semaphore
- the swapchain image could be not ready yet if the semaphores aren't signaled, #946 is possible related
