Kevin Lee 97a1dc360b [2.x] fix: Fixes three test-classloader / jar-handle leaks in the sbt server JVM (#9485) ...

Three independent, pre-existing retention bugs kept the classloader of a
finished in-process test run -- and the open jar handles it holds -- alive
for the rest of the server session.

- JUnitXmlTestsListener: testSuite is an InheritableThreadLocal, so
  threads spawned during a run (e.g. async-framework pool workers) inherit
  a copy of the suite reference that remove() cannot reach.

- TestRecap.collect: the recap is stashed on State.attributes and outlives
  the command, so it must not retain live throwables.

- ClassLoaderCache: loaders evicted from delegate by clearExpiredLoaders
  are unreachable from the map and never enqueued on the ReferenceQueue, so
  neither clear()/close() nor the cleanup thread could ever close them.

SuiteResult now documents the retention hazard on throwables. Adds
deterministic, cross-platform tests for all three severed chains.
