zink: add function for waiting on a specific batch's fence

Browse source 
previously we only had zink_fence_wait(), which just waits on the
current batch to finish, but it may be the case that we don't want to
wait on all batches up to that point, so we can optimize a bit by only
waiting as long as we have to
