  Vulkan: implement swapchain resizing
  
  Vulkan allows a swapchain to be created based off of an older swapchain
  that's still presenting, to support seamless window resizing.  The old
  swapchain will remain alive (though no image can be acquired from it)
  and automatically cleaned once no image is being presented from it.
  
  The retired swapchain can be destroyed once all operations on its images
  are completed.  We store the old swapchain next to the serial of
  submission that's used for CPU throttling and defer the destroy call
  until after `finishToSerial` for that serial is called.
