Increase the timeout of Windows daily build to 90 minutes

[daxian-dbw]

PR Summary

The Windows daily build started to fail intermittently due to timeout (60 minutes by default). When it succeeded, the total time of test run is usually over 50 minutes, so it's better to increase the timeout to 90 minutes to be safe.
