[gtk/split-out-gdk-gtk-source-list-3-24: 6/11] demos/gtk-demo/Makefile.am: Split out source listings

[Chun-wei Fan <fanchunwei src gnome org>]

commit 6c55ada1d609fbbd5b3126812bde85edfe1bb9f5

    demos/gtk-demo/Makefile.am: Split out source listings
    
    This allows us to hace the source listings shared so that we can also
    use it to re-generate demos.h.win32 with the font_features demo, for
    instance, with our build/win32/generate-msvc.mak, where it is not
    included in the MSVC builds by default.
