10.20-1: Stubbed ICU causes issues

Description:

In the packaged wine-staging 10.20-1, stubs for ICU have been added, which causes issues in case the launched Windows application uses ICU. In my case it is latest OpenMPT (1.32.05.00-amd64), which, while it runs in itself without issues, crashes Wine on exit (see attached backtrace from crashed Wine), because it is missing getTZDataVersion. Other programs I tried do not make use of this, so Wine exits without crashing.

Additional info:

At Wine Gitlab, there are three commits to 10.20 AFTER Arch compiled and packaged, which revert the ICU stubs (see below).

• package version(s): wine-staging 10.20-1
• config and/or log files: backtrace-20251203-0859.txt
• link to upstream bug report, if any: "Revert ICU" commits: https://gitlab.winehq.org/wine/wine/-/commit/11e64725b2b3e99a66c916f2092767ddb8815531 https://gitlab.winehq.org/wine/wine/-/commit/6c206800b3fbde24e3a5a34821a7856144469a47 https://gitlab.winehq.org/wine/wine/-/commit/ff0d64407266f7b9780f05845dd34c58c11ecae7

Steps to reproduce:

1. Have wine-staging 10.20-1
2. Use it to run any Windows program that uses ICU, example: https://openmpt.org/download
3. Close the program.
4. Wine crashes with unimplemented functions, in this case getTZDataVersion cannot be found.
