Segmented Button

https://hig.autodesk.com/web/components/buttons

This should be built with the `Button` component as a starting point and using the custom `stylesheet` function to up date the border styles. I think we can either build it so that the component is each button individually with the following props:
- active: to see if it's the active state
- side (or something similar): that tells if the button is left, right, or a middle button

Another way to consider is to group them all together for the user similar to the `Tabs` component,

This should apply theme-data for all current color and density themes (may have to add theme-data)
