…nctions Support for attaching arbitrary metadata for consumption by stream notifier functions got broken in php#19024 when the previous `zval ptr` got changed to `zend_fcall_info_cache *fcc`, making the data specific to the `user_space_stream_notifier`. Fix this by changing the field to `void *ptr`, avoiding the indirection through a `zval`, but preserving the ability to store arbitrary data. If necessary to support different types than `IS_PTR`, extensions can heap-allocate a `zval` to store within `->ptr` as a minimal change to keep compatibility with PHP 8.4 or lower.
