[GSK-1888] Avoid to send nullable values in callable from ML worker to Backend

[Inokinoki]

Description

Add a pre-check in ML worker for Database constraints, referring to:

• ai.giskard.domain.Callable
• ai.giskard.domain.TestFunction
• ai.giskard.domain.DatasetProcessFunction
• ai.giskard.domain.SlicingFunction
• ai.giskard.domain.TransformationFunction

So that the badly-made callable functions will not be sent to the backend (pydantic will raise an error).
