Make sure Serialization.currentTransportInformation is always set, #25067

* The ThreadLocal Serialization.currentTransportInformation is used for serializing local
  actor refs, but it's also useful when a serializer library e.g. custom serializer/deserializer
  in Jackson need access to the current ActorSystem.
* We set this in a rather ad-hoc way from remoting and in some persistence plugins, but it's only
  set for serialization and not deserialization, and it's easy for Persistence plugins or other
  libraries to forget this when using Akka serialization directly.
* This change is automatically setting the info when using the ordinary serialize and deserialize
  methods.
* It's also set when LocalActorRefProvider, which wasn't always the case previously.
* Keep a cached instance of Serialization.Information in the provider to avoid
  creating new instances all the time.
* Added optional Persistence TCK tests to verify that the plugin is setting this
  if it's using some custom calls to the serializer.
