[icu] Add reminder to install autoconf-archive

[MonicaLiu0311]

Fixes #38005.
By user request, add a reminder to install autoconf-archive on non-windows machines.

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• ·Any fixed CI baseline entries are removed from that file.~
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

I canceled the CI Pipeline run because it only added a reminder and did not change the build process.

Disapproval.
When you need autoconf-archive, you also need additional packages.

Disapproval. When you need autoconf-archive, you also need additional packages.

So do you think it's better to keep the current status or add other additional packages to the reminder? Or is there another plan? Looking forward to your reply.

So do you think it's better to keep the current status

I don't think the current status is acceptable. There is even a guideline that ports should print such hints. I wonder why it took so long to see action. It has been reported several times IIRC.

or add other additional packages to the reminder?

Yes, please. There is prior art. For example python3.

Or is there another plan?

There is no plan. However, I still think that the current way of adding these warnings is immature. The ports should just declare dependencies and delegate actions to a shared facility. But what we get is each port carrying a (different) copy of explicit instructions for installing dependencies.

Again.
