Windows builds (e.g., `aarch64-pc-windows-msvc / 3.14 / freethreaded+pgo`) are taking >1 hour

It looks like the `aarch64-pc-windows-msvc / 3.14 / freethreaded+pgo` builds time out occasionally:
* https://github.com/astral-sh/python-build-standalone/actions/runs/17378961342/job/49331901837
* https://github.com/astral-sh/python-build-standalone/actions/runs/17407971471/job/49417635039

and even the latest build on `main` barely avoided the 1 hour timeout at 54 mins:

I don't know if this timeout is a configuration option somewhere or what can be done to speed things up, but I've noticed it seems to happen somewhat often. I haven't done an analysis of other builds, but it makes sense to me that the 3.14 optimised Arm Windows build would take the longest
