[jdk17] RFR: JDK-8266313 (JEP-356) - RandomGenerator spec implementation requirements tightly coupled to JDK internal classes

[Jim Laskey]

The wording of the @implSpec referred to internal methods in the description. The patch rewords the @implSpec to be more descriptive of the algorithm than the methods used.
