Adopting CSS logical properties

[zarahzachz]

CSS has a new syntax called logical properties that decouple spacing from direction, which better supports non-LTR languages.

When we evaluate our spacing throughout the design system, it might be worthwhile to adopt logical properties as part of that work.

Worth noting: This adoption would pose a breaking change to our API as our utility classes (and some component props) use directional-based language (e.g., ds-u-margin-left--X) in the current API.
