feat(connector-corda): add initial set of JvmObject factory functions

[petermetz]

1. These functions are used so more easily construct the JSON representation
   of JVM objects (references and primitive values) that we need to define when
   interacting with the Corda JVM connector (which is used for Corda v4 ledgers)
2. This is not a comprehensive set but more like a trailblazing initial
   implementation to showcase how to create and use these factory functions.
