[C++] Dictionary "delta" building logic in builder_dict.h produces invalid arrays

    Description

      Looking at the unit tests for the dictionary delta logic – the arrays that are produced by subsequent invocations of Finish yield DictionaryArray instances with partial dictionaries. I think this is misleading (I was surprised to find this while working on ARROW-6861). We should develop a different approach to computing dictionary delta.
