[jdk25u-dev] RFR: 8365065: cancelled ForkJoinPool tasks no longer throw CancellationException

[Roland Mesde]

Backporting JDK-8365065: Cancelled ForkJoinPool tasks no longer throw CancellationException. Fixes the exception propagation and tests. Based on the original bug it is a regression and it last worked in version 17.0.16. Ran GHA Sanity Checks (passed), jtreg tier1 tests (passed) and related tests (passed) on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

(Passed) - make test-tier1
(Passed) - make test TEST=test/jdk/java/util/concurrent

Results are attached.
