No consistency check when compaction filter is enabled in stress test (#12291)

Summary:
**Context/Summary:**
[Consistency check between Multiget and Get](https://github.com/facebook/rocksdb/blob/d82d179a5edc57e7de395e5db6f224d53e87c0cd/db_stress_tool/no_batched_ops_stress.cc#L585-L591) requires snapshot to be repeatable, that is, no keys being protected by this snapshot is deleted. However compaction filter can remove keys under snapshot, e,g,[DBStressCompactionFilter](https://github.com/facebook/rocksdb/blob/d82d179a5edc57e7de395e5db6f224d53e87c0cd/db_stress_tool/db_stress_compaction_filter.h#L59), which makes consistency check fail meaninglessly. This is noted in https://github.com/facebook/rocksdb/wiki/Compaction-Filter - "Since release 6.0, with compaction filter enabled, RocksDB always invoke filtering for any key, even if it knows it will make a snapshot not repeatable."

This PR makes consistency check happens only when compaction filter is not enabled in stress test

Pull Request resolved: https://github.com/facebook/rocksdb/pull/12291

Test Plan:
- Make the stress test command that fails on consistency check pass
```
