gtk-demo: Create new textbuffers for new source/info texts
This is so we can prepare these buffers without them being set on the widgets yet and only gtk_text_view_set_buffer() them afterwards. And this in turn gets rid of all the a11y events we were needlessly emitting. https://bugzilla.gnome.org/show_bug.cgi?id=694406
