[SPARK-26816][CORE][TEST] Add XORShiftRandom Benchmark ## What changes were proposed in this pull request? - The benchmark of `XORShiftRandom.nextInt` vis-a-vis `java.util.Random.nextInt` is moved from the `XORShiftRandom` object to `XORShiftRandomBenchmark`. - Added benchmarks for `nextLong`, `nextDouble` and `nextGaussian` that are used in Spark as well. - Added a separate benchmark for `XORShiftRandom.hashSeed`. Closes #23752 from MaxGekk/xorshiftrandom-benchmark.
