Make CertificateValidationEventArgs and CertificateUpdateEventArgs constructors public

[tomaszras-intive]

Proposed changes

Currently there is a way to implement CertificateValidationEventHandler and CertificateUpdateEventHandler but because of CertificateValidationEventArgs and CertificateUpdateEventArgs have only internal constructors, there is no way to create these EventArgs objects for unit testing purposes. Making these constructors public will unblock this important scenario.

Related Issues

• Fixes CertificateValidationEventArgs constructor should be public to allow unit testing custom certificate validation handlers. #2324
