Fix C++ compile errors in aruco.h

- aruco_drawDetectedCornersCharuco: avoid ternary between _InputArray and
  _InputOutputArray (noArray()); use if-assignment instead
- aruco_ArucoDetector_refineDetectedMarkers: entity() does not accept
  std::vector<int>*; use _OutputArray + if-assignment for recoveredIdxs
