[lworld] RFR: 8372261: [lworld] Augment vmTestbase array tests with large flat arrays

[Leonid Mesnik]

Please review following fix that add  Byte[], Boolean[] and Integer[] arrays to garbageProducers and use them in random(arrays) producers and added few configurations to ArrayJuggle3 using these new producers.

Also change some memory objects from primitive arrays to Integer/Byte arrays if preview is enabled to stress flattened arrays.
