Fix write conflict (#1170)

### What problem does this PR solve?

1. Delete conflict check.
2. Refactor compaction conflict check.
3. Refactor conflict with dml and ddl.
4. Fix bug: hnsw insert in parallel with search.
5. Pass test "test_insert_delete_update_parallel_vec",
"test_insert_delete_ddl_parallel", "test_chaos"

TODO: pass unit test "test_hnsw_index_buffer_obj_shutdown" (skip it in
this pr)
TODO: to pass benchmark test, use wrong row count

### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)
- [x] New Feature (non-breaking change which adds functionality)
- [x] Refactoring
- [x] Test cases
- [x] Other (please describe): github workflow script
