Add dynamic eyebrow support for records

Why are these changes being introduced:

* Initial implementation only had placeholder text for the eyebrow
  above the title in search results.
* Dynamic eyebrow support for Timdex and Primo records was requested.

Relevant ticket(s):

* https://mitlibraries.atlassian.net/browse/USE-221

How does this address that need:

* Adds eyebrow to Timdex and Primo record normalization.
* Updates search result partials to display eyebrow if present.

Document any side effects to this change:

* These are unlikely to be the final values for the eyebrows, but they
  provide a starting point for further refinement based on feedback.
