Consider exposing metrics from JDK24 VirtualThreadSchedulerMXBean visually

[tmiddlet2666]

In JDK24, there are metrics regards virtual threads in VirtualThreadSchedulerMXBean.

You should consider adding some visualization support for these JDK24 metrics to VisualVM or via a plugin.

This would help monitor / manage VT this as people adopt this new release.
