RFR: 8225354: serviceability/jvmti/ModuleAwareAgents/ThreadStart failed with Didn't get ThreadStart events in VM early start phase! [v3]

[Serguei Spitsyn]

> The test incorrectly expects that some system threads must be started in the `early JVMTI_PHASE_START` phase. However, there is a race here and it is possible that the `JVMTI_PHASE_LIVE` phase is reached before any system thread has been started. There is no way to fix the test so, it is being removed.

Serguei Spitsyn has updated the pull request incrementally with one additional commit since the last revision:

  review: remove the ModuleAwareAgents/ThreadStart test as there is no way to fix it
