RFR: 8339668: Parallel: Adopt PartialArrayState to consolidate marking stack in compact GC

[Zhengyu Gu]

Please review this patch that adopts `PartialArrayState`introduced by [JDK-8337709](https://bugs.openjdk.org/browse/JDK-8337709) to consolidate `_oop_task_queues` and `_objarray_task_queues` into single `_marking_stacks`.

The change mirrors Kim's [JDK-8311163](https://bugs.openjdk.org/browse/JDK-8311163) work, therefore, there are methods can be consolidated and simplified, but I would like defer to a followup CR.
