Standardize display logic for all facets

[jacobthill]

Some facets in DLME, like 'Type' and 'Language' have language specific display logic e.g. if a record has values 'Type' for Arabic and English, it displays only the English ones when the user is navigating the English view, and only the Arabic ones when the user is navigating in the Arabic view. This is the desirable behavior for all facets, if possible.

Other facets like 'Spatial' will display Arabic and English values for the same record in both views e.g. https://dlmenetwork.org/en/library/catalog?f%5Bagg_data_provider_en%5D%5B%5D=British+Library.+India+Office+Records+and+Private+Papers&f%5Bcho_type_facet.ar-Arab_ssim%5D%5B%5D=%D9%86%D8%B5%3A%D9%85%D8%B3%D9%84%D8%B3%D9%84%D8%A7%D8%AA&f%5Bspatial%5D%5B%5D=%D8%A7%D9%84%D8%AE%D9%84%D9%8A%D8%AC+%D8%A7%D9%84%D8%B9%D8%B1%D8%A8%D9%8A&f%5Bspatial%5D%5B%5D=Persian+Gulf&per_page=96

Ideally, all facets could work like 'Type' and 'Language', but there may be a reason they don't work that way. The data for 'Type' and 'Language' is very consistent; there is always an Arabic and an English value. The data for other fields may sometimes have Arabic, sometimes English, sometimes another language, sometimes multiple languages, etc. If the inconsistency does not prevent us, we should display Arabic script values in the Arabic view and Latin script values in the English view.

I'm happy to talk through this if needed.

Still some big questions about how this should work, since BL thinks that the two language versions of a facet are different values
