Stack from ghstack (oldest at bottom):

This diff is the third part of a series of diffs aiming to split dispatches between multiple command buffers. In this diff, we are tracking the previous semaphore in the context.

A new member variable prev_semaphore_ was added to the Context class. This variable is used to store the semaphore of the previously submitted command buffer.
