Bug 15141: Add MARC21 770/772 Supplement (parent) to OPAC and staff detail pages

Adds the 2 corresponding linking fields to the staff and OPAC detail pages:

770 - Supplement/Special Issue Entry (R)
https://www.loc.gov/marc/bibliographic/bd770.html

772 - Supplement Parent Entry (R)
https://www.loc.gov/marc/bibliographic/bd772.html

To test:
- Catalog records with 770/772 in Koha, examples can be found in the LOC
  documentation.
  - When UseControlNumber is set to Use and $w is added, a link will be built using $w
  - If there is no $w or UseControlNumber is Don't use, a link will be build using the title
- Verify that they display nicely in the OPAC and staff detail pages
