Fix write conflict (infiniflow#1170)
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 - [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
