added cogwheel tests for navy-async configurations

Summary:
This change adds three more cogwheel tests related to the Navy's async io configuration and/or
multiple clean region threads configuration

* cogwheel_cachelib_async: Navy async with io_uring
* cogwheel_cachelib_async_sync_comp: Navy async with sync completion mode (i.e., qdepth 1)
* cogwheel_cachelib_consistency_navy_with_reinsertion_multiple_clean_threads:
Navy with reinsertions, multiple region_manager threads, and consistency check
