Allow AliasedObjectType adding to UseNodesToAddCollector

[pincher2012]

Feature Request

I want create Rector that import missed imports for doctrine annotations for example:

declare(strict_types=1);

+use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class Entity
{
}

I found out that I can add new imports via UseNodesToAddCollector. UseNodesToAddCollector can only use FullyQualifiedObjectType as input, but can return AliasedObjectType. Moreover some annotations do not take into account that UseNodesToAddCollector can return AliasedObjectType

I think that UseNodesToAddCollector must be able to accept AliasedObjectType as input.

May be we should introduce interface for FullyQualifiedObjectType and AliasedObjectType.

I think that this code will be more semantic

if ($this->shouldAddUse($phpDocInfo)) {
-    $this->useNodesToAddCollector->addUseImport(new FullyQualifiedObjectType('Doctrine\ORM\Mapping as ORM'));
+    $this->useNodesToAddCollector->addUseImport(new AliasedObjectType('ORM', 'Doctrine\ORM\Mapping'));

    return $node;
}

May be I even could provide PR after some research.
