[Enhancement]: simplify hybrid_search instead of calling get_sql and then execute sql

[hnwyllmm]

Description

In client_base.py::_collection_hybrid_search, it calls DBMS_HYBRID_SEARCH.GET_SQL first to get the sql, and then executes the sql to get the result.
However, we can call DBMS_HYBRID_SEARCH.SEARCH to retrieve the result directly.
For more information, please refer to SEARCH DOC
