Revisit #9118 for compaction outputs (#9480)

Browse source 
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.
