MutableArrayData::extend does not copy child values for ListView arrays

[vegarsti]

When MutableArrayData::extend is called on a ListView array, it copies the offsets and sizes buffers but does not copy the underlying child values. The result is an array whose offsets/sizes point into an empty values array.

  // Build a ListViewArray: [[1, 2], null, [3]]
  let list: ListViewArray = /* ... */;

  let data = list.to_data();
  let mut mutable = MutableArrayData::new(vec![&data], false, 3);
  mutable.extend(0, 0, 3);

  let result_list_view: &ListViewArray = /* ... */;

  // Offsets and sizes were copied, but values array is empty:
  //   offsets: [0, 2, 2], sizes: [2, 0, 1], values.len(): 0
