[folks] eds: Add an Edsf.Persona.in_google_personal_group property

    eds: Add an Edsf.Persona.in_google_personal_group property
    
    This is set whenever the persona is in the âMy Contactsâ group in Google
    Contacts, which is normally exposed by EDS as being in the âPersonalâ
    category. This system group canât be reliably detected normally as âPersonalâ
    is translated by EDS. This caused problems for gnome-contacts, hence the
    new API.
    
    The new API requires EDS 3.5.3 at runtime, and will always be false
    otherwise.
