Follow-up to #8932.

#8932 kept every partially qualified name as written. That caused a regression: a node copied from another file (e.g. an inherited constructor param typed Sub\Dep in the parent file) keeps its partially qualified originalName, so it stayed fully qualified in the child instead of being imported.

This PR:

• Reverts the guard in ClassNameImportSkipper and restores the 10 fixtures, so plain partially qualified names (use App\Field; Field\TextField) are imported again, as before [CodingStyle] Keep partially qualified names as written on import names #8932.
• Keeps the regression fixtures for aliased names, now with the real Doctrine and Symfony stubs. These are already kept as written:

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

#[ORM\Column]
#[Assert\Length(max: 255)]
public string $name;

The fixtures cover attributes, annotations, @var, new, ::class, param/return types, and an alias used next to a direct import of the same class.
