[C++] Array::View fails for string/utf8 as binary

[asfimport]

I encountered this

-- Arrow Fatal Error --
Invalid: Can't view array of type string as binary: not enough buffers for view type
In ../src/arrow/array.cc, line 1049, code: CheckInputAvailable()
In ../src/arrow/array.cc, line 1100, code: impl.MakeDataView(out_field, &out_data)

when trying to add a BinaryWithRepeats function to RandomArrayGenerator

  std::shared_ptr<Array> out;
  auto strings = StringWithRepeats(size, unique, min_length, max_length,
                                   null_probability);
  ABORT_NOT_OK(strings->View(binary(), &out));
  return out;

It looks like utf8 <-> binary view simply aren't tested in array-view-test
