Allow to continue when fail to configure Windows Defender (#103454)
Windows Defender will soon be removed from the AMI. Without the service, the step fails with the following error:
```
Set-MpPreference : Invalid class
At C:\actions-runner\_work\_temp\1f029685-bb66-496d-beb8-19268ecbe44a.ps1:5 char:1

+ CategoryInfo : MetadataError: (MSFT_MpPreference:root\Microsoft\...FT_MpPreference) [Set-MpPreference],
CimException
+ FullyQualifiedErrorId : HRESULT 0x80041010,Set-MpPreference
```
For example, https://github.com/pytorch/pytorch-canary/actions/runs/5267043497/jobs/9521809176. This is expected as the service is completely removed.
