[glibmm] Glib::VariantBase::cast_dynamic(): Remove noexcept(false)

[Kjell Ahlstedt <kjellahl src gnome org>]

    Glib::VariantBase::cast_dynamic(): Remove noexcept(false)
    
    noexcept(false) has the same meaning as no noexcept specification, but
    Doxygen adds "noexcept" instead of "noexcept(false)" in the detailed
    description of the method, which is confusing. Bug 789329
