headline: Refactor APIs for Vectorization Operand Mapping
tldr: The APIs `vect_slp_child_index_for_operand` and `vect_get_operand_map` are updated to simplify how operand information is accessed during vectorization.

This commit cleans up the vect_slp_child_index_for_operand and vect_get_operand_map APIs by having them receive a stmt_vec_info object, which elides the need for a separate gather-scatter flag argument. This simplifies the API and improves code clarity in the vectorization process.
