LUCENE-9358: remove unnecessary tree rotation for the one dimensional case
(#1481)
Change the way the multi-dimensional BKD tree builder generates the
intermediate tree representation to be equal to the one dimensional case to
avoid unnecessary tree and leaves rotation

> This is a spin-off of LUCENE-9807. The reason we need to rotate the one
> dimensional tree is that the expected representation when we pack the index
> is different to the tree generated by the one dimensional logic. It would be
> easy to harmonise how we generate this tree representation to be the same in
> the one dimensional case and the multi-dimensional case and therefore change
> the index-packing logic to work on that representation.
