Explicitly use functions from the Configurator namespace

[mpdude]

This adds namespace imports for functions from the Symfony\Component\DependencyInjection\Loader\Configurator namespace on top of the generated files.

Technically, those imports are not necessary at runtime, since the functions can be resolved correctly without.

However, it makes a difference for tools like ComposerRequireChecker that have to rely purely on static analysis (SA).

With SA alone, function imports may be ambiguous (see maglnet/ComposerRequireChecker#193 (comment)).

By adding these imports, we add more static information.

Thanks.

I don't think that's in the spirit of the feature. We're in the Symfony\Component\DependencyInjection\Loader\Configurator namespace so we don't have to import classes and functions. I'll keep it open while I think about it.
