http-client-java, bug fix on parent resource rename

[weidongxu-microsoft]

fix problem caused by #8176

It causes problem on ExtensionResource, that systemData is not included in the result resource. However it is not reproducible from azure-http-specs test.

The current solution is to limit this rename to AutoGenerated class alone.

What's the issue with ExtensionResource?

The systemData is not generated in the resource model.
https://github.com/Azure/azure-sdk-for-java/pull/46397/files#diff-0e5be5ec57a2461a9144e5985ad6526bd1137653c8210f20141b856143e3ac31

To be frank, I still not sure what happened. It seems related to the rename process, as we map ExtensionResource to ProxyResource in codegen.
https://github.com/microsoft/typespec/blob/main/packages/http-client-java/generator/http-client-generator-mgmt/src/main/java/com/microsoft/typespec/http/client/generator/mgmt/transformer/ResourceTypeNormalization.java#L251-L252

Also, there is a "replace parent" logic, when name is not same.

However, I still unsure why these causes this missing of systemData.
Here, the current fix is just limit the scope of my previous rename, so basically it only handle ##AutoGenerated# class.

Let me know if you think up something.
