[BUG]: Fails to compile on php 8.5

[akansc]

Describe the bug

Fails to compile on 8.5 due to missing ext/standard/php_smart_string.h

The 8.4 already had the deprecation message and got removed in 8.5 completely.

php-8.4.12.tar.gz# tail -n2 ./ext/standard/php_smart_string.h
/* Header moved to Zend. This file is retained for BC. */
#include "zend_smart_string.h"
