    meson: Use summary instead of manually built string
    
    It simplifies the code, and allows us to have some consistency
    between projects (either inside and outside GNOME, mind you).
    
    I took the liberty to rename and reword some of the options so
    that they actually describe which ones are optional, and also
    which ones are hard dependencies detected at build time.
