RFR: 8279598: Provide adapter from RandomGenerator to Random [v4]

[Yasser Bazzi]

> Hi, could i get a review on this implementation proposed by Stuart Marks, i decided to use the https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/random/RandomGenerator.html interface to create the default method `asRandom()` that wraps around the newer algorithms to be used on classes that do not accept the new interface.
> 
> Some things to note as proposed by the bug report, the protected method next(int bits) is not overrided and setSeed() method if left blank up to discussion on what to do with it.
> 
> Small test done on https://gist.github.com/YShow/da678561419cda8e32fccf3a27a649d4
