[jdk17u-dev] RFR: 8318467: [jmh] tests concurrent.Queues and concurrent.ProducerConsumer hang with 101+ threads

[Roland Mesde]

Backporting JDK-8318467: Tests concurrent.Queues and concurrent.ProducerConsumer hang with 101+ threads. Adjusted the capacity of the queues. Updated the copyright notice, which had a merge conflict. Ran GHA Sanity Checks (1 unrelated test failure - java/lang/ProcessBuilder/Basic.java#id0) and adjusted tests (passed). Patch is clean.
