Adds fields that are meant to be imported statically to the engine. When adding fields be sure that
the classes of those fields are added to the {@link #addClassImports(Class[])} or
{@link #addClassImports(Collection)}. If they are not added then the certain {@code ScriptEngine} instances
may have problems importing the methods (e.g. gremlin-python).
