    Revert "meson: simplify builtin_immodules build option"
    
    This reverts commit 749a58ab26bc01381d66ccefdd3aa42a34353e70.
    
    This maintains feature parity with the autotools build. To achieve the
    equivalent of --with-included-immodules=wayland,
    -Dbuiltin_immodules=wayland,waylandgtk can be used instead.
