Add semaphores to the command buffer submit api

Browse Source 
Allow to pass in semaphores to wait for before executing
and to signal after executing the command buffer. This
just exposes the capabilities of the underlying Vulkan
api. Update all callers to pass no semaphores, for now.

We will use this in the future.
