RFR: 8308752: Generational ZGC: Avoid final marking through stack chunks

Mon May 29 15:38:03 UTC 2023

Single generation ZGC switches marking strength to strong unconditionally when marking through loom stack chunks, as there is no support for final marking through nmethod oops. We missed doing the same thing in generational ZGC, which is an oversight. This patch fixes that.
