[gtk+/wip/css: 125/154] styleproperty: Use a custom resolve function for colors

    styleproperty: Use a custom resolve function for colors
    
    We want to make sure to fall back to the initial value of the property
    if resolving fails.
    
    This is kinda tricky, because the initial value itself might need
    resolving, too.
