Merge two queue submissions in Queue::SubmitImpl()

Currently Queue::SubmitImpl() may cause two queue submissions, one is
because of Tick() call which will submit pending commands if there are.
The other one is after converting frontend commands to backend command
buffer. Queue::SubmitImpl() will submit converted commands. However
usually queue submissions are expensive, so merge those two queue
submissions into one by not calling Tick() before converting frontend
commands, so pending commands and recorded commands can be submitted
together. After that, we call Tick() to resolve callbacks and perform
bookkeeping operations (deallocating memory for passed operations,
etc).
