Please review this fix to how patched modules are being handled when linking from the run-time image. During review of [JDK-8311302](https://bugs.openjdk.org/browse/JDK-8311302) it was pointed out that module patching should be detected earlier and the link should get aborted in that case.
This patch implements it, by looking at the `jdk.module.patch.0` property like [other code in the JDK](https://github.com/openjdk/jdk/blob/2c1e4c381615ce52276f4bf331a1e7a845af4b6e/src/hotspot/share/cds/cdsConfig.cpp#L282) does. After this patch module patching is being detected before any archives are being read or the actual linking process starts (contrary to the previous solution).
Testing:
- [x] GHA testing (mac aarch64 test failures are infra related)
- [x] Local testing of existing test, which covers it
Thoughts?
