Migrate utility mixins in deprecated.scss
Created in !3990 (merged), the deprecated.scss
file contains unconventional utility mixins that we didn't have a clear migration path for when we deprecated the collection they were part of.
This issue should be the very last migration in the epic. We'll review the remaining mixins in deprecated.scss
and assess the necessary migration path.
