RFR: 8335288: SunPKCS11 initialization will call C_GetMechanismInfo on unsupported mechanisms [v2]

[Valerie Peng]

> Can someone help review this fix? Changed the required-mechanism check by checking if the particular mechanism is inside the list of enabled supported mechanisms. This should be more reliable than calling C_GetMechanismInfo(..) on the required mechanism given vendors may return various sorts of error codes.
