Yanqin Jin fdf2a0d7eb Fix a compaction bug for write-prepared txn (#9061)
Summary:
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9061

In write-prepared txn, checking a sequence's visibility in a released (old)
snapshot may return "Snapshot released". Suppose we have two snapshots:

```
earliest_snap < earliest_write_conflict_snap
```

If we release `earliest_write_conflict_snap` but keep `earliest_snap` during
bottommost level compaction, then it is possible that certain sequence of
events can lead to a PUT being seq-zeroed followed by a SingleDelete of the
same key. This violates the ascending order of keys, and will cause data
inconsistency.
