[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`).
