Emit partial types

[AArnott]

For the data types, please emit them with the partial keyword so we can add members to them outside the generated code.

Whats your use case? What do you consider data types? Records?

[AArnott]

Data types would be the unifii dictionary defined types. I believe you emit these as records.
Non-data type examples: types that surround methods that provide the interop or infrastructure support. No need for partial there.
