[KZN-3416] async loading for SingleSelect

[Kitty-Al]

What

PR focuses on supporting asynchronous data loading, infinite scroll, and accessibility announcements for loading and empty states. Storybook and tests have been updated to demonstrate these new capabilities.

Async Data Loading & Infinite Scroll

• Added support for async loading and infinite scroll in SingleSelect via the loadItems prop and useAsyncList, including debounced server-side filtering and dynamic loading of more items on scroll.
• Updated the List component to handle loading and no-results states, with new styles for these states. Included translations for the default loading and no results
• Refactored ClearButton due to needing a controlled input and selected state
• Added @react-stately/data dependency to support async list management
