Coming soon: jtreg 8

[Christian Stein]

JDK folk,

This is a general heads-up that jtreg 8 is ready for use and
that we should soon update JDK to use it.

Starting with jtreg 8, AsmTools 8.1 [1] and JUnit 5.13.3 [2]
are bundled. With that comes support for strict fields and
parameterized test classes.

Find a listing of noteworthy changes at [3].

Also starting with version 8, jtreg is compiled with JDK 17.
Yet, it still only requires a recent release of JDK 11 to run
it.

The plan is to integrate [JDK-8361950]: Update to use jtreg 8
in August 2025. After the integration of the PR you must use
jtreg 8 to run tests in the mainline JDK repository.

Finally, thanks to everyone who has helped thus far!
