RFR: 8294693: Add Collections.shuffle overload that accepts RandomGenerator interface [v2]

[Tagir F. Valeev]

> Java 17 added RandomGenerator interface. However, existing method Collections.shuffle accepts old java.util.Random class. While since Java 19, it's possible to use Random.from(RandomGenerator) wrapper, it would be more convenient to provide direct overload shuffle(List<?> list, RandomGenerator rnd).
