RFR: JDK-8257856: Make ClassFileVersionsTest.java robust to JDK version updates

[Joe Darcy]

Change the test in question to generate its data programmatically to avoid updates with each JDK release. (Assuming this gets pushed before the start of JDK 19, I'll revert the customary changes to the test in set of start-of-19 updates.)

Running the test, it does probe the same set of values:

STDOUT:
