Add Component Token to all components

[julrich]

We currently lack one major feature of kickstartDS in our implementation here: Component Token.

We should walk through all the components, and define useful Component Token that need to be exposed to potential users of this Design System (DSA). Those token should be specific to DSA, it shouldn't just be passed down token taken from underlying components (e.g. Mosaic -> Storytelling).

This also enables useful integration of our Component Token-addon for Storybook.
