RFR: 8266130: convert Thread-SMR stress tests from counter based to time based [v4]

[Daniel D.Daugherty]

> The Thread-SMR project added counter based tests for various APIs.
> See "JDK-8167108 inconsistent handling of SR_lock can lead to crashes".
> 
> Time based tests are more appropriate for stress kits so I'm
> updating the counter based tests to be time based instead.
> 
> Two of the updated tests have shaken out failures that are tracked by:
> 
>     JDK-8264605 vmTestbase/nsk/jvmti/SuspendThread/suspendthrd003/TestDescription.java failed with "agent_tools.cpp, 471: (foundThread = (jthread) jni_env->NewGlobalRef(foundThread)) != NULL"
> 
>     JDK-8266593 vmTestbase/nsk/jvmti/PopFrame/popframe011 fails with "assert(java_thread == _state->get_thread()) failed: Must be"
> 
> These updated tests are tested via Mach5 Tier[134567].
> They have also been test by my Stress Kit runs for jdk-17+2[0-5].
