[gtk+/wip/otte/shader: 16/51] gsksl: Redo declaration "decorator" parsing



commit ba851f6ed571a2d8efb3df9f95af7ba41a84aefc

    gsksl: Redo declaration "decorator" parsing
    
    Instead of parsing into a list of flags, have an array of values that
    can be set to certain values. This way, we can reuse it for layout()
    contents.
