[jdk11u-dev] RFR: 8293563: [macos-aarch64] SA core file tests failing with sun.jvm.hotspot.oops.UnknownOopException [v2]

[Christoph Langer]

> The backport of [JDK-8248194](https://bugs.openjdk.org/browse/JDK-8248194) introduced the testing of core files in test/hotspot/jtreg/serviceability/sa/ClhsdbFindPC.java. This can cause issues which we are seeing on MacOS arm64. With this backport, these seem to be gone.
> 
> The fix does not exactly fit into the 11u-dev codebase, so I had to make several adpatations.
