Address some timeout issues in the Windows CI

This change disables Windows Defender real-time monitoring on the test
workers, and increases the test timeout to 20 minutes (default is 10).

The Windows Defender real time monitoring feature scans any newly
created files for malitious contents. This takes up a lot of CPU when
expanding image archives, which contain lots of files. The CI has been
timing out due to the fact that tests take longer than 10 minutes. This
change should address that issue.
