[jdk21u-dev] RFR: 8322809: SystemModulesMap::classNames and moduleNames arrays do not match the order

[Goetz Lindenmaier]

Resolved SystemModulesPlugin.java due to context (ClassFile.of() <--> Classfile) 

The patch is based on the commit to 23, the version for 22/22.0.1 is identical.

I can reproduce the error with the test, and the patch fixes the issue. 

I had to adapt the tests because "8317620: Build JDK tools with ModuleMainClass attribute" is missing in 21.
jdk.jfr has no main, so I exclude it from the tests.
