[php-src] Issue #23353: ext/dom: `DOMDocument::adoptNode()` leaves dangling wrappers under later siblings on 8.3 and 8.4

Issue: https://github.com/php/php-src/issues/23353
Author: alexandre-daubois

### Description

The following code:

```php
<?php
$source = new DOMDocument('1.0', 'UTF-8');
$root = $source->createElement('root');
$source->appendChild($root);

$first = $source->createElement('first');
$first->appendChild($source->createTextNode('first'));
$root->appendChild($first);

$later = $source->createElement('later');
$victim = $source->createTextNode('victim');
$later->appendChild($victim);
$root->appendChild($later);

$destination = new DOMDocument('1.0', 'UTF-8');
$destination->appendChild($destination->adoptNode($root));

unset($destination, $root, $first, $later);
gc_collect_cycles();

echo $victim->data, "\n";
```

Produces a UAF.

When a subtree is adopted into another document, `php_dom_transfer_document_ref()` updates the document reference of every live PHP wrapper in that subtree, but it visits only the `xmlAttr`
nodes and never the value nodes under `attr->children`.

It is already fixed in 8.5 and above by c77a129.
