32-bit Python 3.12.7 subprocess.run() cannot run executables from Windows\System32

Bug report

Bug description:

This does work in the 64-bit Python 3.12.7 (after renaming vcruntime140.dll; see #125872):

PS C:\> py -V:3.12 -c "import subprocess; subprocess.run(['ssh'])"
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]
           [-b bind_address] [-c cipher_spec] [-D [bind_address:]port]

           [-w local_tun[:remote_tun]] destination [command [argument ...]]

I'm assuming that this is because ssh.exe is an ARM executable. Using file in a Git Bash shell:

$ file "C:\Windows\System32\OpenSSH\ssh.exe"
C:\Windows\System32\OpenSSH\ssh.exe: PE32+ executable (console) Aarch64, for MS Windows, 6 sections

Calling an amd64 git does work:

PS C:\> py -V:3.12-32 -c "import subprocess; subprocess.run(['git', 'version'])"
git version 2.47.0.windows.1

$ file "C:\Program Files\Git\cmd\git.exe"
C:\Program Files\Git\cmd\git.exe: PE32+ executable (console) x86-64, for MS Windows, 13 sections

CPython versions tested on:

3.12

Operating systems tested on:

Windows 11 ARM

Reproduisez l’échec avec la commande Python 3.12 32 bits sous Windows 11 ARM, puis inspectez Lib/subprocess.py autour de Popen et _execute_child, en particulier l’appel à _winapi.CreateProcess. Comparez-le aux cas 64 bits et amd64 Git qui fonctionnent ; le travail est terminé lorsque subprocess.run(['ssh']) peut lancer l’exécutable Windows System32 dans la configuration signalée.
