- reduce number of processes from 10 to 5 - reduce the number of files in the sample zip from 10000 to 5000 - make the test use less CPU resources so that it will run in CI with constrained resources - make JIT compiler stop at C1 - disable JMX registration in Log4j2 which showed up in profiling - increase max heap size from 64MB to 96MB to give more head room for GC

Fixes #21291
Fixes #21285
Motivation
NarUnpackerTest is really flaky. See the above isues that this PR fixes.
When investigating the problem, I was able to reproduce the issue by running the test within Docker with constrained resources. There's a 30 second timeout in the shouldExtractFilesOnceInDifferentProcess test for the 10 different processes to complete. This takes much longer since each process uses significant amount of CPU. The fix is to reduce the CPU consumption by reducing the test data size, reducing the number of processes and tuning the JVM parameters for the forked processes.
