Summary: **Context/Summary:** Previously `CompactFiles()` used `RangeOverlapWithCompaction()` to check for conflict when sanitizing input files while later used `FilesRangeOverlapWithCompaction()` to assert for no conflict. The latter function checks for more conflict scenarios than the former does, particularly the ones arising from `preclude_last_level_data_seconds > 0` (i.e, compaction can output to second-to-the-last level). So we ran into assertion violation in `CompactFiles()` like below ``` Assertion `output_level == 0 || !FilesRangeOverlapWithCompaction( input_files, output_level, Compaction::EvaluatePenultimateLevel(vstorage, ioptions_, start_level, output_level))' failed. ``` This PR make `CompactFiles()` used `FilesRangeOverlapWithCompaction()` and return Aborted status upon range conflict instead of crashing (during debug build) or proceed incorrectly (during non-debug build). To do so cleanly, I included a refactoring to make `FilesRangeOverlapWithCompaction()` part of `SanitizeAndConvertCompactionInputFiles()`, replacing `RangeOverlapWithCompaction()`. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12628 Test Plan: New UT crashed before the fix and return correct status after the fix.
