[gtk+/wip/css: 61/154] styleproperty: Move value printing to real properties

    styleproperty: Move value printing to real properties
    
    We can't print shorthands, so don't try.
    In particular, I want to get away from shorthands being representable
    using GValue, and this function kinda requires that.
