Change `Tags` set in Interpreter to hold any metadata / ignored payloads.

[zeeshanlakhani]

Summary

For added flexibility in the interpreter, we can hold on to type information or discarded payload information (e.g. in results) so that we can return more specific runtime values when going from WIT back to IPLD.

Components

• Change Tags from a VecDequeue<String> to VecDequeue<T>.
• Handle additional edge cases.
