> [C++] allow Array to have null buffers when all elements are null

> In the case of all elements of an array being null, no buffers whatsoever
> *need* to be allocated (similar to NullArray). This is a more extreme case of
> the optimization which allows the null bitmap buffer to be null if all
> elements are valid. Currently {{arrow::Array}} requires at least a null
> bitmap buffer to be allocated (and all bits set to 0).
