    [FLINK-8993] [tests] Let general purpose DataStream job uses KryoSerializer via type extraction

    ## What is the purpose of the change
    
    The general purpose DataStream job previously only uses the `KryoSerializer` via a custom state serializer. This PR allows the job to  also use the `KryoSerializer` via Flink's type extraction.
    
    ## Brief change log
    
    - Adapt the state builders to be able to  supply a state class, instead of a state type serializer.
    - Let `DataStreamAllroundTestJob` specify state serializers via state classes instead of a direct custom serializer.
    
    ## Verifying this change
    
    This is a extension to existing end-to-end tests (`test-streaming-savepoint.sh`).
