Add `createDynamicObject` stdlib function. (#1923)
This function takes a user provided `typeID` and arbitrary typed value, and turns them into an existential value whose `witnessTableID` is `typeID` and whose `anyValue` is the user provided value. This allows the users to pack the runtime type id info in arbitrary way.
