Summary: #Summary Quick follow-up from https://github.com/facebook/rocksdb/pull/13816: `CompactFiles()` and `CompactRange()` in CompactionPickers do not run compaction as their names might suggest. What they actually do is create the Compaction object that will be passed to `CompactionJob` to run the compaction. Renaming these two functions to better represent their purposes. Pull Request resolved: https://github.com/facebook/rocksdb/pull/13831 Test Plan: No functional change. Existing CI should be sufficient.
