refactor(build): improve auto-discovery of GUI library sources in build_cleaner.py

- Enhanced the discover_cmake_libraries function to identify decomposed libraries and handle special cases for source variables.
- Updated gui_library.cmake to utilize auto-maintenance markers, streamlining the management of source lists for GUI components.
- Commented out hardcoded CMake source blocks, allowing for dynamic discovery of source files.

Benefits:
- Simplifies the maintenance of GUI library sources by automating updates and reducing manual configuration.
- Improves clarity and efficiency in the build process for GUI components.
