Use Chunk

[adamgfraser]

We have a variety of cases where we are using List for a collection. Unless there is a specific reason we want linear access we should generally be using ZIO's Chunk data type as it provides good performance for a range of operations that require linear or random access and has fast append and prepend.

This ticket is to go through ZIO ZMX and replaces List with Chunk wherever possible.
