RFR: 8289610: Degrade Thread.stop [v2]

[Alan Bateman]

> Degrade Thread.stop to throw UOE unconditionally, deprecate ThreadDeath for removal, and remove the remaining special handling of ThreadDeath from the JDK.
> 
> Thread.stop is inherently unsafe and has been deprecated since JDK 1.2 (1998) with a link to a supplementary page that explains the rationale. Some of the API surface has already been degraded or removed: Thread.stop(Throwable) was degraded to throw UOE in Java 8 and removed in Java 11, and ThreadGroup.stop was degraded to throw UOE in Java 19. As of Java 19, the no-arg Thread.stop continues to work as before for platform threads but throws UOE for virtual threads. The next step in the glacial pace removal is the degrading of the no-arg Thread.stop method to throw UOE for all threads.
> 
> To keep things manageable, the change proposed here leaves JVM_StopThread in place. A separate issue will remove it and do other cleanup/removal in the VM. We have another JBS issue for the updates to the JLS and JVMS where asynchronous exceptions are defined. There is also some remaining work on a test class used by 6 jshell tests - if they aren't done in time then we will temporarily exclude them.
> 
> The change here has no  impact on the debugger APIs (JVM TI StopThread, JDWP ThreadReference/Stop, and JDI ThreadReference.stop). Debuggers can continue to cause threads to throw an asynchronous exception, as might be done when simulating code throwing an exception at some point in the code.
