RFR: 8366893: java/lang/Thread/virtual/stress/GetStackTraceALotWhenPinned.java timed out on macos-aarch64

[Aleksey Shipilev]

GetStackTraceALotWhenPinned test times out every so often in GHA.

The last sightings are on macos-aarch64:


2025-09-04T10:41:29.357879Z => 87894 of 100000
2025-09-04T10:41:30.365534Z => 88105 of 100000

Looks like we are nearly there, just need fewer iterations. I think like with [JDK-8344577](https://bugs.openjdk.org/browse/JDK-8344577), we just need to extend the test check for AArch64 macs as well.

Additional testing:
 - [x] MacOS AArch64 server fastdebug, `java/lang/Thread/virtual/stress`, 10x
