Add UI Icons integration

Problem/Motivation

The UI Icons module is designed as a potential Core solution for providing icons across Drupal. However, the Iconify Icons module does not yet offer integration with the UI Icons module. To ensure that the full spectrum of icon options is available to site builders and administrators, the Iconify Icons module should add a provider to seamlessly integrate with UI Icons.

Integrating Iconify Icons as a provider in the UI Icons module will allow users to easily choose from the vast collection of icons in Iconify while maintaining consistency with Drupal’s core UI functionality.

Proposed resolution

• Add Iconify Icons as a provider option within the UI Icons module.
• Implement the necessary integration between Iconify Icons and the UI Icons API.
• Ensure that the full Iconify icon set is available for selection when using the UI Icons module.
• Provide configuration options in the Iconify Icons module to control which icons are available and how they are displayed.
