Fix opcache preload warning for unlinked anonymous class

This fixes PHP opcache preload warning, caused by https://github.com/php/php-src/issues/10131 .  The warning is now produced when the preload is initiated.

> Can't preload unlinked class Twig\ExpressionParser\Infix\BinaryOperatorExpressionParser@anonymous: Unknown parent Twig\ExpressionParser\Infix\BinaryOperatorExpressionParser

This started with Twig 3.21, when the anonymous class started to be used in ExtensionSet.

This is a similar woraround as is already used in a TwigBridge, as suggested by `@nicolas`-grekas here https://github.com/symfony/symfony/pull/38533
Also similar fix is in API platform: https://github.com/api-platform/core/pull/3827
