support global Symfony DIC function: "service" and "param"

[Haehnchen]

See Symfony PRs:

• Move internal Container configuration from XML to PHP  symfony/symfony#37186
• Use PHP instead of XML as the prefered service/route configuration in core symfony/symfony#36778

Thanks @Haehnchen for the quick support. What I've came across is the problem with factory arguments as described in #1140

Note that they are not global functions. They are namespaced functions (Symfony\Component\DependencyInjection\Loader\Configurator\service & co)
