[mutter] tools/get-state: Add --short

    tools/get-state: Add --short
    
    Often, most of the output consists of a long list of exposed modes for
    each monitor. If --short is passed, only pass modes that has properties.
    In practice, this means "preferred" modes, "current" modes, and
    similarly special cases, which significantly reduces noise.
