RFR: 8272567: [IR Framework] Make AbstractInfo.getRandom() static

[Christian Hagedorn]

To use the dedicated (`private static final`) `Random` object of `AbstractInfo` one needs to use the non-static `getRandom()` method like this:


@Run(test = "myTest")
public void runMethodForMyTest(RunInfo info) {
   int x = info.getRandom().nextInt();
   myTest(x);
}


This simple patch makes `getRandom()` static to provide an easier access to it without the need to specify `RunInfo` as parameter:


@Run(test = "myTest")
public void runMethodForMyTest() {
   int x = RunInfo.getRandom().nextInt(); // or AbstractInfo.getRandom().nextInt()
   myTest(x);
}


Thanks,
Christian
