in favor of the added MakoSystem render_template method. Related changes: * Adds the MakoService to the StudioEditModuleRuntime, PreviewModuleSystem, LmsModuleSystem, and XBlockRuntime * MakoService constructor takes a `namespace_prefix` string, so that the CMS PreviewModuleSystem can render to LMS templates, without needing the special render_from_lms helper method. * ModuleSystem.render_template becomes a read-only property, so the constructor calls and test module systems are updated accordingly. * Adds tests for the MakoService and module system shims.
