fix: properly handle nested local type aliases

[romm]

The following annotation now works properly:

/**
 * @phpstan-type Address = array{street?: string, city: string}
 * @phpstan-type User = array{name: non-empty-string, address: Address}
 */
final class SomeClass
{
    public function __construct(
        /** @var User */
        public $value,
    ) {}
}

(new \CuyZ\Valinor\MapperBuilder())
    ->mapper()
    ->map(SomeClass::class, [
        'name' => 'John Doe',
        'address' => [
            'street' => 'Bron-Yr-Aur',
            'city' => 'SY20 8QA, Machynlleth',
        ],
    ]);
