Revisit #9118 for compaction outputs (#9480)

Summary:
Crash test recently started showing failures as in https://github.com/facebook/rocksdb/issues/9118 but
for files created by compaction. This change applies a similar fix.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9480

Test Plan:
Updated / extended unit test. (Some re-arranging to do the
simpler compaction testing before this special case.)

 ## Unreleased
 ### Bug Fixes
 * Fixed a major bug in which batched MultiGet could return old values for keys deleted by DeleteRange when memtable Bloom filter is enabled (memtable_prefix_bloom_size_ratio > 0). (The fix includes a substantial MultiGet performance improvement in the unusual case of both memtable_whole_key_filtering and prefix_extractor.)
+* Fixed more cases of EventListener::OnTableFileCreated called with OK status, file_size==0, and no SST file kept. Now the status is Aborted.
 
 ### Public API changes
 * Remove HDFS support from main repo.
