windows-2025 seems to fix the flakiness discribed in #127883 — This PR never failed a bors try.
This PR also removes the large runner by splitting it into two free runners, addressing rust-lang/infra-team#189 🥳

Too good to be true? Let's see! My suggestion is to merge this PR and observe how it behaves in the auto branch in the public dashboard over the following weeks.

Additional context

I discussed this change in Zulip as well.

If you want to see a similar PR to this one where x86_64-msvc on windows 2022 fails in CI consistently, see #135483 (comment)

Yes. There's another pr from me in the merge queue right now that touches this makefile.

Once that PR is merged I'll update this PR and make it ready for review 👍

From my understanding, this should be a flaky error.
I will run this job in the bors try to confirm.
