Cleanup hung Windows processes (#94357)
Follow https://stackoverflow.com/questions/40585754/powershell-wont-terminate-hung-process to see if the hung python process can be killed completely
```
C:\Jenkins\Miniconda3\python.exe -bb test_ops.py -v --use-pytest -vv -rfEX -x --reruns=2 --shard-id=0 --num-shards=2 "-k=not linalg_cholesky" --import-slow-tests --import-disabled-tests
```
The command `Get-Process -Name $process -ErrorAction Stop | Stop-Process -Force` doesn't stop this process as expect
### Testing
1. Spinning up a local python process on Windows runner `C:\Jenkins\Miniconda3\python.exe debug.py`
2. See that the process is runnning
```
Get-WmiObject -Class Win32_Process -Filter "Name LIKE 'python%' AND CommandLine LIKE '%debug%'"
