Description:
------------
When serializing any `Reflector` instance, but also `ReflectionType` and `ReflectionGenerator` (which are the only two classes of the reflection extension not implementing `Reflector` BTW), then the unserialized value is unusable and throws `Error`: "Internal error: Failed to retrieve the reflection object" on any method calls.

This is legit, but instead of this late error, these should not be serializable in the first place.

Note that IteratorIterator and RecursiveIteratorIterator also shouldn't be serializable.
(and by the way, they're missing a private __clone method, same for ReflectionGenerator)

Fixed for master only (PHP 7.4), as this may potentially break some code unintentionally serializing reflection objects.
