Move some interop tests to the public interface test project (#1767)

most of those interop tests illustrate how to interact with objects from
popular libraries such as Newtonsoft.Json, System.Text.Json and dynamic
objects such as ExpandoObject.

because this can be a valuable reference for Jint users, they should not
depend on any internals (which would be off limits for callers.)
