community: Add support for SAP HANA Vector hnsw index creation (#27884) **Issue:** Added support for creating indexes in the SAP HANA Vector engine. **Changes**: 1. Introduced a new function `create_hnsw_index` in `hanavector.py` that enables the creation of indexes for SAP HANA Vector. 2. Added integration tests for the index creation function to ensure functionality. 3. Updated the documentation to reflect the new index creation feature, including examples and output from the notebook. 4. Fix the operator issue in ` _process_filter_object` function and change the array argument to a placeholder in the similarity search SQL statement. --------- Co-authored-by: Erick Friis <erick@langchain.dev>
