The brand new worker does not have any existing ActorInfo for the actors.

[shanicky]

Describe the bug

During the development of the alter resource group feature, I found that when an existing materialized view is altered to a completely new worker, the newly created actor cannot obtain the actor info of the upstream actor, resulting in a failure to start.

After checking the code, it seems that only the newly created actor is broadcasted.

             broadcast_info: new_actors_location_to_broadcast.clone(),

This issue may not have existed before refactoring broadcast.
