Non-internal SerializationVisitorInterface implements internal VisitorInterface

Hey there,

currently switching over from phpstan to psalm and realized that psalm addresses my SerializationVisitorInterface implementation of using internal methods from jms/serializer.

I had to verify that and stumbled on the @internal annotation within the VisitorInterface.

I think, this is due to the fact, that no one should directly depend on that interface (as already addressed in other issues).
Sadly, there is no way of not implementing the methods of VisitorInterface when implementing SerializationVisitorInterface.

I had some similar issues in another package of mine and fixed it, by also adding the methods to the depending interface.

Before

After

https://3v4l.org/a0HPa
https://psalm.dev/r/7f54d8996a

I wonder if this might be a scenario for this package without having a BC break?

I've seen #1161 but not sure if this is related. I just want to get rid of psalms error that we are using internal methods which are actually not internal.
