Fix serialization verification problem with Akka.IO messages (#4974)

* Fix serialization verification problem with Akka.IO messages

* Wrap naked SocketAsyncEventArgs in a struct that inherits INoSerializationVerificationNeeded

* Make the wrapper struct readonly

* Expand exception message with their actor types

* Update API Approver list
