feat: Implement LoadingButton error state (#428)

* Add error svg icon

*  Implement error state in LoadingButton

- Refactor styles to reuse for success and error states
- Dynamically render success or error icons and remove visible prop

* feat(components): rename svgIcon prop and update story and snapshots

"svgIcon" prop is renamed "as" for clarity (uses Emotion as prop) after review

* test(components): test LoadingIcon error state with snapshot
