Change radii implementation on EllipseShape

Instead of "Round outline" as in the current QtDS components we want to have full radius support for Ellipse and all it shapes it can become. I've tried to show all the combination in the image below. Still wasn't sure how Figma does the rounding on the lips of the pacman shape as shown in the screenshot. The red circle has the same radius as the Ellipse, it fits in the center but not on the ends. You can see the Figma project here.
