Review Comment:
   I know you're still working here, but just a bump that I don't think we want 
`array_view->variadic_buffer_view` to exist, since it will involve a 
potentially very large allocation on `ArrowArrayViewSetArray()`. Those are 
buffer views that we can materialize on demand by either adding 
`ArrowBufferView ArrowArrayViewVariadicBuffer(array_view, i)` or 
`ArrowArrayViewBuffer(array_view, i)`.
