This patch adds an "Essentials" asset library that is bundled with Blender. Also see #103620. At build time, the `lib/assets/publish` folder is copied to `datafiles/assets` in the build directory. In the UI, the "Essentials" library can be accessed like other custom asset libraries with the exception that assets from that library cannot be linked. The immediate impact of this is that Blender now comes with some geometry node groups for procedural hair grooming. Pull Request #104474
