Yu Zhang 6a3da5635e Add documentation to some formatting util functions (#11674)
Summary:
As titled, mostly adding documentation. While updating one usage of these util functions in the external file ingestion job based on code inspection.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/11674

Test Plan:
```
make check
```

Note that no unit test was added or updated to check the change in the external file ingestion flow works. This is because user-defined timestamp doesn't support bulk loading yet. There could be other missing pieces that are needed to make this flow functional and testable. That work is separately tracked and unit tests will be added then.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

CircleCI Status

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Questions and discussions are welcome on the RocksDB Developers Public Facebook group and email list on Google Groups.
