add windows OpenSSL 1.1 jenkinsfile builder (#3624)

* add windows OpenSSL 1.1 jenkinsfile builder

I tested this before submitting. You can see the output here:
https://ci.cryptography.io/blue/organizations/jenkins/openssl-release-1.1/detail/openssl-release-1.1/8/pipeline

Once this merges we can switch the jenkins job to pull this directly
from the repository. Unfortunately the job does not get created
automatically in jenkins, so that's a new step in building our infra
