Add border width to ttk frame

[ObaraEmmanuel]

Could you apply similar fixes for other containers that may not be visible when added, all of them in legacy as well as native such as

• frame
• panedwindow
• canvas (legacy)
• vertical/horizontal panedwindows (native)

Yes, when I find some time.

Should only take 10 minutes.
