fix: timetick cannot push forward when upgrading (#42567)
issue #42492

- streamingcoord start before old rootcoord.
- streaming balancer will check the node session synchronously to avoid
redundant operation when cluster startup.
- ddl operation will check if streaming enabled, if the streaming is not
enabled, it will use msgstream.
- msgstream will initialize if streaming is not enabled, and stop when
streaming is enabled.
