Finally, finish encoding commands by calling `copyEncoder.finish()` and submit
those to the GPU device command queue. The queue is responsible for handling
submissions done via `device.getQueue().submit()` with the GPU commands as
submissions done via `device.defaultQueue.submit()` with the GPU commands as
arguments. This will atomically execute all the commands stored in the array in
order.
