However, some recent changes (e.g. [JDK-8240239](https://bugs.openjdk.org/browse/JDK-8240239)) to `gcCause.hpp` were not simultaneously reflected in `GCCause.java`. This patch updates `GCCause.java` to keep sync with latest `gcCause.hpp`.

Changes requested by stefank (Reviewer).

gcCause.hpp has the Shenandoah and ZGC blocks swapped. Could you fix it in this change as well?
