This was already done internally in ICU in rdar://107702106
This reflects changes published as GB-18030-2022
This was proposed as a change to the standard at https://github.com/whatwg/encoding/issues/312
This fixes an assertion when running encoding tests on macOS Sonoma and iOS 17,
and I added test coverage specific to the 18 changed code points.
