[improve][broker] checkTopicExists supports checking partitioned topic without index

[nodece]

Motivation

The checkTopicExists method doesn't support checking the partitioned topic without the partition index.

Modifications

Refactor the checkTopicExists method:

1. If the topic is persistent and includes -partition-, find the topic from the /managed-ledger path.
2. If the topic is found in the managed-ledger path, return true, otherwise continue finding.
3. Use the getPartitionedTopicName() name to query the metadata of the topic from /admin/partitioned-topics path, and return true if metadata.partitions is greater than 0, indicating that it is a partitioned topic and exists, otherwise go and find if the non-partitioned topic exist, the persistent topic exists in the /managed-ledgers path, the non-persistent topic only exist in the broker's topics map.

Verifying this change

Added test.

we should keep the original logic(check isPersistent first ) to avoid the topic is non-partitioned non-persistent
