[dyno] start to map owned to _owned module code

[arezaii]

This adds support for mapping owned to the _owned record implementation in module code. Resolves https://github.com/Cray/chapel-private/issues/6157.

The change includes similar patterns for _owned and _shared but does not quite work for _shared yet. I believe we'll have more info on what _shared needs next once nested functions resolved.

For now the _shared test is commented out.
