Uuid & IncludedSpaceView types are now serializable in python (#5372

)

### What

* part of #4167

Steps towards serializable `ViewportBlueprint`. Adjusted structure a
bit: it used to be `IncludedSpaceViews` (plural) it's now
`IncludedSpaceView` (singular) and we store a component array on the
`ViewportBlueprint archetype.
Also, uuid needed some extra love on codegen as well.
