Code Modernization: Only call libxml_disable_entity_loader() in PHP < 8.

Browse Source 
This function has been deprecated in PHP 8.0 because in libxml 2.9.0, external entity loading is disabled by default, so this function is no longer needed to protect against XXE attacks.

Props jrf.
Fixes #50898.
