[php-src] Issue #8756: ext-oci8: `oci_new_descriptor()` triggers dynamic property deprecation

Issue: https://github.com/php/php-src/issues/8756 Author: derrabus ### Description The following code: https://github.com/doctrine/dbal/blob/e15d05d08172ceeb4f55066feed48d688fdb0250/src/Driver/OCI8/Statement.php#L75 Resulted in this output: > Creation of dynamic property OCILob::$descriptor is deprecated https://github.com/doctrine/dbal/runs/6850136105?check_suite_focus=true But I expected this output instead: The piece of code that PHP complains about does not write any property directly but calls oci_new_descriptor() which is supposed to return a new OCILob instance. I don't feel like I could avoid the deprecation. ### PHP Version PHP 8.2.0-alpha1 ### Operating System Ubuntu 20.04
