Previously, we haven't added this because there were plans to use these declarations at a higher abstraction level where one declaration potentially contains more than one socket. This hasn't happened yet, and we are also using other ways to achieve dynamic socket amounts (using dynamic declarations). Therefore, it is reasonable to simplify the code by storing the integer socket type in the declaration directly. Pull Request: https://projects.blender.org/blender/blender/pulls/119691
