Update GB-18030 encoding table
Browse files Browse the repository at this point in the history 
https://bugs.webkit.org/show_bug.cgi?id=257770
rdar://110353061

Reviewed by Myles C. Maxfield.

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 whatwg/encoding#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.
