Summary: When compaction filter determines that a key should be removed, it updates the internal key's type to `Delete`. If this internal key is preserved in current compaction but seen by a later compaction together with `SingleDelete`, it will cause compaction iterator to return Corruption. To fix the issue, compaction filter should return more information in addition to the intention of removing a key. Therefore, we add a new `kRemoveWithSingleDelete` to `CompactionFilter::Decision`. Seeing `kRemoveWithSingleDelete`, compaction iterator will update the op type of the internal key to `kTypeSingleDelete`. In addition, I updated db_stress_shared_state.[cc|h] so that `no_overwrite_ids_` becomes `const`. It is easier to reason about thread-safety if accessed from multiple threads. This information is passed to `PrepareTxnDBOptions()` when calling from `Open()` so that we can set up the rollback deletion type callback for transactions. Finally, disable compaction filter for multiops_txn because the key removal logic of `DbStressCompactionFilter` does not quite work with `MultiOpsTxnsStressTest`.
