This PR adds functionality for state passing between operators, enabling better coordination and data flow in complex workflows. The changes primarily involve updates to serialization logic and the introduction of mechanisms for operators to share and access the state during execution. Key Highlights: 1. Implementation of state serialization and deserialization. 2. Integration of state passing into operator workflows. This update is essential for a more dynamic and responsive pipeline processing. Introduce `State` as a type of `Marker`. The `State` class has the following methods: 1. `add(key: String, value: Any, valueType: AttributeType): Unit ` 2. `get(key: String): Any`
