[Twig] Autocomplete functions/filters from Twig extensions with new Symfony 7.3 attributes

[kira0269]

With the Symfony 7.3 release come two new attributes to configure Twig extensions: AsTwigFunction and AsTwigFilter.
Using these attributes does not enable autocompletion in twig templates. Keeping extending AbstractExtension still works though.
