Add an orientation option to CTkSegmentedButton

[PhilipNelson5]

This feature adds the option vertical=False to the CTkSegmentedButton constructor. A "vertical" segmented button uses a vertical layout instead of the default horizontal layout.

Partially addresses #852

@TomSchimansky is the official documentation source available for MRs? I'd be happy to update the docs for this feature if it is accepted.

I just noticed that progressbar and scrollbar uses the convention orientation="horizontal" or "vertical", I'll update this to be consistent.
