Label update and consolidation of CITGM jobs

[targos]

FYI @nodejs/citgm, @nodejs/releasers, I made the following changes to the Jenkins CITGM jobs, hopefully to make them more reliable:

• Test only on the latest available OS version. That means for example that I removed fedora-last-latest, and replaced rhel8 with rhel9.
• Fix the inline shell scripts to download arm64 binaries for labels that end with -arm64. This should make the arm64 Windows tests faster (and cover arm64 instructions too) and fix the errors that we've been having on macOS
• Use the same labels on all relevant jobs (except for alpine-latest-x64, which I only added to citgm-smoker because we don't have official binaries to download for the other jobs.
• On Windows, set both vs2019 (for v18 and v20) and vs2022 (for v22 and v23)

Updated jobs (you can see the new set of labels on each of those pages):

@StefanStojanovic I am not sure about Windows. Since in the regular CI, the build from source is never done on arm64 hardware, I set "fake" labels on the citgm-smoker job (iiuc, win-vs2022-arm64 will build on x64 hardware). On the other two jobs, I tried to select labels so that it runs on x64 hardware for versions <=20 and on both x64 and arm64 for newer versions.

citgm-smoker (v22): https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/3525/ ✅ ⚠ (arm64 windows is not really arm64)
citgm-smoker (v18): https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/3526/

https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/3525/nodes=win-vs2022-arm64/console is doing an x64 build. Those Windows labels are difficult to get right...
