Added the following logic: * in `enqueue_nd_range_kernel`, we catch all generated events for each queue. * those events get cleared when calling `queue.finish` or `cl.wait_for_events`. * if a kernel argument's queue's events are not in the current `wait_for`, we complain.
Uses WeakSet to store events so we don't have to worry when they get destroyed. The check for out of sync events is also more strict: we now store the event per (buffer, op) as well as per queue and only check events that are still valid in both and only for the current buffer.
