At vkQueueSubmit time, for each batch with timeline semaphores to signal, append cmd_buffers with feedback cmds to update the counter value in its respective feedback slot. Since multiple signals on the same semaphore could be pending at the same time across batches/vkQueueSubmits, src slots and commands are allocated on demand. These src slots can be reused after they've been signaled (if the current semaphore counter is greater/equal than the src value) and are cleaned up on vkDestroySemaphore.
