fix(eds-core-react): use legacy token for Autocomplete chip outline

The chip outline in Autocomplete used a new token variable
(--eds-color-accent-12) that is only available via the new CSS
variables import. Stable components should work with only
tokens.css, so this switches to the legacy token with fallback.
