Set consoleAllocationPolicy=detached to shim manifest

[sitiom]

As of Windows 11 24H2, Windows added support for CONSOLE subsystem applications to opt out of automatic console allocation (learn.microsoft.com/en-us/windows/console/console-allocation-policy).

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <application>
    <windowsSettings>
      <consoleAllocationPolicy xmlns="http://schemas.microsoft.com/SMI/2024/WindowsSettings">detached</consoleAllocationPolicy>
    </windowsSettings>
  </application>
</assembly>

With that entry, the application will only get a console if it inherits one.

This would be useful for applications that have this value in their manifest, and it does not break existing behavior.
