[GIT-PULLS] [php-src] PR #22654: Readonly properties must be re-locked after clone-with

Pull Request: https://github.com/php/php-src/pull/22654
Author: NickSdot

Found this while stealing code for #22588. The following code:

```php
readonly class Test {
    public public(set) int $a = 1;
    public public(set) int $b = 2;
}

$cloneWith = clone(new Test(), ['a' => 3]); // only a
$cloneWith->b = 4; // why legal?
var_dump($cloneWith);
}
```

Resulted in this output:
```
object(Foo)#2 (2) {
  ["a"]=>
  int(3)
  ["b"]=>
  int(4)
```

But I expected this output instead:
```
Error: Cannot modify readonly property Test::$b
```
