RFR: 8361103: java_lang_Thread::async_get_stack_trace does not properly protect JavaThread

[Alex Menkov]

The fix updates `java_lang_Thread::async_get_stack_trace()` (used by `java.lang.Thread.getStackTrace()` to get stack trace for platform and mounted virtual threads) to correctly use `ThreadListHandle` for thread protection.

Testing: tier1..5
