Is your feature request related to a problem? Please describe.

Originally used in iOS/Android and Windows Apps like Office, segmented controls allow switching between views (like a TabStrip) or configuring settings/options with optional multi-selection.

It looks like there is finally some movement on this by Microsoft:

• Grouped selection support microsoft/microsoft-ui-xaml#2310 was the original discussion in WinUI. This was horribly renamed and they refused to fix it... the discussion was largely killed because the team doesn't understand the request or have the time/resources to take on stuff like this anymore.
• 🧪 [Experiment] Segmented CommunityToolkit/Labs-Windows#392 Picks up this issue and actually provides a prototype of the controls. This is something to watch closely as the styling is very good.
• [Feature] SegmentedControl CommunityToolkit/Labs-Windows#314 Is the discussion.

Describe the solution you'd like

I first want to know if a contribution of these controls will be accepted in this project? If so, I will plan to port them over at some point in the future once upstream stabilizes. Eventually, I would expect Avalonia itself to get controls like this so perhaps that would be next step.

Describe alternatives you've considered

There are several alternative designs possible but none as concise.
