Disable db_stress features incompatible with unsynced data dropping when sync_fault_injection=1 (#10559)

Summary:
The features that cannot work with disable_wal=1 due to unsynced data dropping (ingest_external_file_one_in and enable_compaction_filter) similarly cannot work with sync_fault_injection=1. This PR prevents those features from being used together with sync_fault_injection=1.
