refactor: replace WMIC with PowerShell for CPU architecture detection

[tahaghafuri]

• Replace deprecated WMIC command with modern PowerShell
• Use Get-CimInstance instead of WMIC to access Win32_Processor
• Maintain compatibility with existing code by keeping same output format
• Improve compatibility with newer Windows versions
• No changes to core program logic

Thank you! So far we had no powershell requirement in the SDK, but that shouldn't be an issue, and it's certainly simpler than the JScript alternative:

var service = GetObject("winmgmts:");
var procs = service.InstancesOf("Win32_Processor");
if (procs.Count >= 1) {
    WScript.StdOut.WriteLine(procs.ItemIndex(0).Architecture);
}

or PHP:

<?php

$locator = new COM("WbemScripting.SWbemLocator");
$service = $locator->ConnectServer(".", "root\cimv2");
$procs = $service->InstancesOf("Win32_Processor");
if ($procs->Count >= 1) {
    echo $procs->ItemIndex(0)->Architecture;
}
