Summary: Symfony collectionCascaded and collectionCascadedDeeply fields security bypass

Details: When using the Validator component, if `Symfony\\Component\\Validator\\Mapping\\Cache\\ApcCache` is enabled (or any other cache implementing `Symfony\\Component\\Validator\\Mapping\\Cache\\CacheInterface`), some information is lost during serialization (the `collectionCascaded` and the `collectionCascadedDeeply` fields). As a consequence, arrays or traversable objects stored in fields using the `@Valid` constraint are not traversed by the validator as soon as the validator configuration is loaded from the cache.
