deser array tree from a vortex array

[onursatici]

Summary

Add support for serialising a ArrayNode tree into a vortex array, with array stats. Before we always serialised these into flatbuffers that were appended to the tail of the serialised array buffers. This PR adds the scaffolding to get a vortex array that can later at read time used to deserialise the buffers into ArrayRef's.

Main user of this would be the array tree layout, which will land in a followup PR
