ROU-12485: add icon library support on CSS use-cases

[BenOsodrac]

This pull request reorganizes and centralizes the handling of icon-related styles and markup across the SCSS codebase. The main change is the introduction of a new icon-library-odc foundation file, which consolidates icon definitions and related styles previously scattered throughout the project. This results in a cleaner, more maintainable structure, and removes redundant or duplicated icon CSS from individual widget and pattern files.

Key changes include:

Icon Library Centralization:

• Added a new file 01-foundations/icon-library-odc containing all icon-related styles, including FontAwesome icon usage for accordions, search, submenu arrows, dropdowns, and sortable table icons. This file now serves as the single source of truth for icon styles.
• Updated ODC SCSS entrypoints (gulp/ProjectSpecs/ScssStructure/Root.js, src/scss/ODC.OutSystemsUI.scss) to include the new icon library section and import the file, ensuring icons are available throughout the ODC platform. [1] [2] [3] [4]

Widget and Pattern SCSS Cleanup:

• Removed redundant or now-centralized icon CSS from widget and pattern SCSS files, such as accordion caret, search input backgrounds, submenu header icons, dropdown arrows, and sortable table icons. These have all been moved to the new icon library file. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17]

Project Structure and Build Updates:

• Updated build configuration and project spec files to reference the new icon library and removed the now-obsolete table-sortable-icon widget section. [1] [2] [3]

These changes improve maintainability by ensuring all icon styles are defined in a single location, reducing duplication and making it easier to update or extend icon usage in the future.
