Add comprehensive nil type JSON unmarshal tests

This commit restructures and extends the JSON unmarshal tests for nil types to cover more data types, including boolean, byte slice, float32, float64, int, int64, string, and various unsigned integers. Each test ensures proper handling of value retrieval, nil checks, and reset behavior, enhancing the robustness of the unmarshal functionality.
