Derive tui_win_info from tui_gen_win_info

This changes tui_win_info to derive from tui_gen_win_info, rather than
having a tui_gen_win_info as a member.  This removes a layer of member
access from the entire TUI, which is why this patch is so large.  This
change will enable further removal of switches based on window type.
