Fix MpscLinkedQueue GC issues (#7799)
* Refactor MpscLinkedQueue.poll
Handle empty queue first, then share most of the
implementation for non-empty scenarios (spin and
non-spin).
* Unlink dead nodes in MpscLinkedQueue
Similar to
https://github.com/JCTools/JCTools/blob/master/jctools-core/src/main/java/org/jctools/queues/MpscLinkedQueue.java#L120,
null out the next pointer in the discarded consumer node
when polling from the queue. If not, we leave behind a (potentially long)
chain of connected garbage nodes. If we're unlucky (for example one of
the early nodes is promoted to old generation, triggering nepotism),
this can cause GC issues as now we have a long linked list which must be
marked by young collections.
Reproducer:
```
import io.reactivex.rxjava3.internal.queue.MpscLinkedQueue;
public class MpscLinkedQueueGC {
    public static void main(String[] args) {
        MpscLinkedQueue<Integer> queue = new MpscLinkedQueue<>();
        for (int i = 0; i < 10; i++) System.gc(); // tenure consumer node
        while (true) {
            queue.offer(123);
            queue.poll();
        }
    }
}
```
```
