Initializes and preloads Windows Certificate Store classes.
Call this method on Windows to initialize Windows Certificate Stores, internally created and used by TElCertificateValidator, and preload them with certificates.
This is a relatively lengthy operation (it takes several seconds) which needs to be done once per instance of Certificate Validator class.
Preloading the stores explicitly speeds up further validation of certificates.
This method makes sense only when UseSystemStorages property is set to true.
