Improve performance of array_find() etc (#18157)

This avoids destruction logic for the common case, avoids some copy, and
adds an optimization hint.

For this script:
```php
$array = range(1, 10000);

$result = 0;
for ($i = 0; $i < 5000; $i++) {
    $result += array_find($array, static function ($item) {
            return $item === 5000;
    });
}
var_dump($result);
```
