This adds a new vk_queue_submit object which contains a list of command buffers as well as wait and signal operations along with a driver hook which takes a vk_queue and a vk_queue_submit and does the actual submit. The common code then handles spawning a submit thread if needed, waiting for timeline points to materialize, dealing with timeline semaphore emulation via vk_timeline, etc. All the driver sees are vk_queue.submit calls with fully materialized vk_sync objects which it can wait on unconditionally. This implementation takes a page from RADV's book and only ever spawns the submit thread if it sees a timeline wait on a time point that has not yet materialized. If this never happens, it calls vk_queue.submit directly from vkQueueSubmit() and the thread is never spawned. One other nicety of the new framework is that there is no longer a distinction, from the driver's PoV, between fences and semaphores. The fence, if any, is included as just one more signal operation on the final vk_queue_submit in the batch.
