[jdk8u-dev] RFR: 8212155: Race condition when posting dynamic_code_generated event leads to JVM crash [v2]

[Kerem Kat]

> Backport of [JDK-8212155](https://bugs.openjdk.org/browse/JDK-8212155).
> 
> The patch did not apply cleanly due to a merge conflict. The original code `JvmtiThreadState::state_for(JavaThread::current())` had already been refactored to `JavaThread::current()->jvmti_thread_state()` in this branch.
> 
> I have also removed the `@requires vm.jvmti` tag from the test, as it is not supported by the jtreg version in JDK 11.
> 
> For JDK 8, `DynamicCodeGeneratedTest.sh` was added as the runner, which compiles the library first.
> 
> The `DynamicCodeGeneratedTest` was confirmed to sometimes crash without this patch and passes with it.
