    meson: Be able to build the static library
    
    Don't use the meson's shared_library() target, but the library() one, so
    we are able to change the library type through the default_library
    option.
    
    Also disable introspection if the static library is requested as the
    gnome.generate_gir() needs an executable or a shared library.
