Add JSON serialization methods for Task and TaskResult classes

Feature Description

Add JSON serialization methods for Task and TaskResult classes. Both ways, from and to JSON.

Problem

The task framework already enforces call args and kwargs to be JSON serializable. However, there are not handy functions that can serialize and deserialize a TaskResult. This burden currently falls on the backends, which will always be awkward with the frozen dataclasses.
