Bug 24269: Adjust C4::Heading to generate headings from auth tags

To test:
1 - Be using Elasticsearch
2 - Check that field 150 is mapped to 'Match-heading' or add it (the subfields don't matter)
3 - Add a topic term authority record like "150 $aCats$vFiction"
4 - Add a 650 with $aCats and $vFiction and  $e depicted to a bibliographic record
5 - Run the linker for the bib
    perl misc/link_bibs_to_authorities.pl --bib-limit "biblionumber=89" -v
6 - Confirm the record is not correctly linked to the record
7 - Apply patch
8 - Reindex authorities for ES
    perl misc/search_tools/rebuild_elasticsearch.pl -v -d -a
9 - Run the linker and confirm record is correctly linked
    perl misc/link_bibs_to_authorities.pl --bib-limit "biblionumber=89" -v
