CI: use free runners for 4 fast windows jobs

I noticed those jobs are faster than the others. The longest is 1 h 30 min, while the [auto builds](https://github.com/rust-lang-ci/rust/actions?query=branch%3Aauto) usually take > 2h 20 min.

I'll try how much time windows free runners take for these jobs to see if we can use them instead of the large one.

Goal: these jobs shouldn't take longer than the slowest jobs of the auto build.
