Surfman tests freeze on "chains sm-no-wgl sm-angle-builtin"

[sagudev]

runs:
https://github.com/servo/surfman/actions/runs/12647771161/job/35240794466
https://github.com/servo/surfman/actions/runs/12630057884/job/35189122571

also happens on main

I suspect there might be mutex deadlock.

surfman/src/platform/windows/angle/device.rs

Line 81 in 300789d

let result = dxgi::CreateDXGIFactory1(

I am wondering if removing serial and only limiting test threads would work.

I think the real problem is tear down (dropping) that poisons something.
