enhance: CMD-182 design tokens (#200)

* enhance: CMD-182 do not use `-rgb` css vars

* chore: remove redundant style

%x-overlay--callout already does this

* fix: CMD-182 do not use var in rgb

- not supported by Safari v15*
- not polyfilled by postcss-relative-color-syntax

* Supported by v16. Once v18 coems ut, we can use var in rgb, because we only need support latest 2 major versions of common browsers.

* fix: CMD-182 more not use var in rgb

* chore: CMD-182 flag old color vars as deprecated

* fix: CMD-182 rgb relative color syntax
