Improving fill Function to Support Negative Indices

[wondonghwi]

Currently, the fill function in lodash and the toFilled function in esToolkit support negative indices. However, the fill function in esToolkit does not support negative indices. Enhancing the fill function to support negative indices will ensure consistency with the fill function in lodash and the toFilled function in esToolkit.

To maintain consistency, we propose enhancing the fill function in esToolkit to support negative indices, similar to the fill function in lodash and the toFilled function in esToolkit. For more details, please refer to the discussion here.

Would it be okay if I proceed with the improvements to the fill function?
