also for issue: #46166
add ack_sync_up flag into broadcast message header, which indicates that
whether the broadcast operation is need to be synced up between the
streaming node and the coordinator.
If the ack_sync_up is false, the broadcast operation will be acked once
the recovery storage see the message at current vchannel, the fast ack
operation can be applied to speed up the broadcast operation.
If the ack_sync_up is true, the broadcast operation will be acked after
the checkpoint of current vchannel reach current message.
The fast ack operation can not be applied to speed up the broadcast
operation, because the ack operation need to be synced up with streaming
node.
e.g. if truncate collection operation want to call ack once callback
after the all segment are flushed at current vchannel, it should set the
ack_sync_up to be true.
TODO: current implementation doesn't promise the ack sync up semantic,
it only promise FastAck operation will not be applied, wait for 3.0 to
implement the ack sync up semantic. only for truncate api now.
