gh-152680: Detect virtualization on Windows in pythoninfo (GH-152824)

Use WMI to detect virtualization on Windows.

Replace wmic command with _wmi module to get the operating system caption and
version.

The wmic tool is deprecated since January 2024:

For example, it's no longer installed in Windows images on GitHub
Action.

Fix also run_command(): no longer try to spawn a subprocess if the
platform doesn't support subprocess. It avoids logging run_command()
errors.
