RCP-240327A: Computed state

[dr-orlovsky]

layers: consensus
consensus: fast-forward

In schema, we can have a global and owned state, which is computed from the contract state. Possible use cases for this: inflationary/deflationary assets,

This can be added as an additional global and owned state type enum variant, and may contain a reference on a transforming script, underlying data type (if any), resulting data type, and the data source (result register).
