Initializes and Apple Mac OS X Certificate Store classes.
Call this method on Mac OS X to initialize Apple Mac OS X 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 the Certificate Validator class.
Preloading the stores explicitly speeds up further validation of certificates.
Use of this method makes sense only when UseSystemStorages property is set to true.
