Suppress PHP 8 deprecation warning in startup
Summary: Ref T13588. See D21497. As of PHP 8, the XML entity loader is disabled by default and the libxml_disable_entity_loader function is deprecated. Thus suppress the deprecation warning for now; we could skip the function call, but this is safer.
- Still works with PHP 7.
- No more deprecation message with PHP 8.
