Windows - Support WDAC Audit Mode (#84730)

Fix up bug when attempting to run any module on a Windows host that has
been configured with WDAC and Dynamic Code Security in audit mode. This
does not enable WDAC support with signed scripts so Ansible will still
not pass the audit events but it no longer fails to run.
