feat: support s390x and powerpc

[Zxilly]

This patch adds support for s390x and powerpc.

According https://github.com/nodejs/node/blob/main/BUILDING.md#platform-list , only powerpcle available on Linux. So we always use uv-powerpc64le-unknown-linux-gnu

According to https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners/about-self-hosted-runners#architectures those are not supported architectures for GitHub Action runners. Am I missing something?

IBM has written a fork that supports s390x, and there seems to be some work to support it on the main branch as well.

While writing this patch, I added powerpc support by the way, as I noticed that uv provides pre-builds for these platforms.

Thank you for the insight. Is this fork public and can you share a link? Also, do you have a running infrastructure available where you can test this on? This would help a lot in making sure we are releasing high quality.

I have deployed this fork on my own project, check out the https://github.com/Zxilly/go-size-analyzer/blob/5e0591e1219e2af888c74d7e5e3e9f0bbe7585d2/.github/actions/setup-script/action.yml#L26

It works as expected, shown in https://github.com/Zxilly/go-size-analyzer/actions/runs/13348482963/job/37281949011 , the self-hosted runner is a s390x runner.

The runner fork was at https://github.com/anup-kodlekere/gaplib . There's some patches in build-files
