Long standing replace inflights post completion can be archived before cleaning for KEEP_LATEST_FILE_VERSIONS cleaner policy.

For KEEP_LATEST_FILE_VERSIONS cleaner policy, file versions are only maintained for active file groups not for replaced file groups.

Since, earliestCommitToRetain is null for KEEP_LATEST_FILE_VERSIONS policy, last clean instant can be considered as a lower bound, since the cleaner would have removed all the file groups until then. But there is a catch to this logic, while cleaner is running if there is a pending replacecommit then those files are not cleaned.

## JIRA info

- Link: https://issues.apache.org/jira/browse/HUDI-6351
- Type: Bug

No file or test is named. Start by tracing cleaner handling for KEEP_LATEST_FILE_VERSIONS, especially how pending replace commits interact with earliestCommitToRetain and the last clean instant. Done means replaced file groups are not archived before their pending replace commits are cleaned.
