Add Library of Congress NAF as Author identifier (#9812)

* Add Library of Congress NAF as Author identifier

Adds Library of Congress Name Authority File (LC NAF) as an Author identifier.

The `label` has been shortened to just “Library of Congress” to
avoid having an obscenely long label in the drop-down lists and
also avoid obscure acronyms (“NAF”) in it that are likely to
cause more confusion than clarity.

The URI identifiers given by LoC themselves start with “http://” but I
have opted to use “https://” for the `url` so patrons etc. won’t need a
redirect or similar to get to the page.

Closes #9791

* Add auto select for LOC NAF Author identifiers

Adds an entry for `loc_naf` (Library of Congress Name Authority File)
identifiers to the `identifierPatterns` lookup table to enable
autoselection when entering the identifiers.

* Update LoC NAF identifier label+name
