mergeOneField now hands the segments' CAGRA indexes to the cuVS merge API, falling back to the vector based merge when the merged rows cannot be lined up with the merged flat vectors. Deleted documents are dropped through a row, which needs a new CagraIndex.merge overload taking a BitSet. Also cleans up some merge overloads on CuVSProvider and CagraIndex. Closes NVIDIA#1078
