Bug

What is the expected behavior?

CDK shipped with scss files for packages like overlay and a11y.

What is the current behavior?

As of 7.0.0, the distributed scss files are no longer there—only the prebuilt ones.

What are the steps to reproduce?

See https://unpkg.com/@angular/cdk@6.4.7/ vs https://unpkg.com/@angular/cdk@7.0.0/.

What is the use-case or motivation for changing an existing behavior?

Access to the scss files allows overriding the variables provided before applying by the mixin. The prebuilt ones don't.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Angular CDK 7.0.0

Is there anything else we should know?
