[fix][broker] Fix bug causing loss of migrated information when setting other localPolicies in namespace

[hrzzzz]

Motivation

#21367 introduced the migrated field in localPolicies to indicate whether the topics under a namespace have been migrated in the blue-green cluster migration feature.

In #9598, it is specified that when updating the field content of localPolicies, a new object needs to be created instead of updating the original object.

After the addition of the migrated field in #21367, there has been no synchronization of modifications in other places that update localPolicies. This could lead to the loss of the migrated content during other operations on localPolicies, such as setting the namespaceAntiAffinityGroup, etc.

Modifications

1. Synchronize the migrated content in the places where localPolicies are updated
2. When updating the migrated field of localPolicies, do not modify the original object
