fix(material/chips): set correct cursor on interactive chips (#26171)

We were always setting the `mdc-evolution-chip__action--presentational` class on the primary chip action to avoid some very specific `:hover` styles from MDC, but the side effect was the correct cursor wasn't being applied to the action anymore.

With the new token-based API we don't generate the `:hover` styles at all so we can re-add the class and fix the cursor.

Fixes #26050.
