KAFKA-19234: broker should return UNAUTHORIZATION error for non-exist…

[Joker-5]

In https://github.com/apache/kafka/pull/15968/files, we changed the authorization logic slightly. If a produce request includes a topic name that doesn't exist and is not authorized, it now returns an UNKNOWN_TOPIC_OR_PARTITION error. Since topic name is sensitive information, it should return a TOPIC_AUTHORIZATION_FAILED error as before that PR.

    else if (!metadataCache.contains(topicPartition))
      nonExistingTopicResponses += new TopicIdPartition(topicId, topicPartition) -> new PartitionResponse(Errors.UNKNOWN_TOPIC_OR_PARTITION)

@FrankYang0529 Sorry, after I created this PR, I noticed you reassign this jira to yourself and I did not notice the comment in the jira. So could you add a co-author tag in your comment, thanks so much.

@Joker-5 I've added you as a co-author to #19635 (see the description). This will be included when merging the code. Therefore, I'm closing this PR as a duplicate. Thanks!
