Slow windows tests

[danepowell]

Windows tests runs are brutally slow compared to linux. Trying to figure out why.

• Windows runners are consistently extremely slow compared to Linux and macOS actions/runner-images#7320
• Windows Server 2022 builds are taking 4x longer than on Windows Server 2019 actions/runner-images#5166

I think actions/runner-images#7320 is the culprit. Any CPU-intensive task (composer install, tests) just takes forever. It might be a noisy-neighbor problem, as our midnight cron jobs never take long at all, but PR tests during the day can take 2-5x longer than Ubuntu.
