Enable relevant thread pool events in Windows

[LakshanF]

It seems like some IO threadpool events (IOPack, IOEnqueue, and IODequeue) can be enabled for windows in NativeRuntimeEventSource.PortableThreadPool. Given that NativeAOT now has EventPipe, we should do this work to help customers with their diagnostics scenarios.

[kouvel]

The portable thread pool implementation should already be raising the events on Windows and Unixes (though last I checked a while back, they weren't working yet). #88894 is adding the raising of some events for the Windows thread pool implementation.

Aside from IOPack, which seemingly is not raised currently on NativeAOT Windows

[LakshanF]

ThreadPoolIOWork event is not yet working in Windows (either with the UseWindowsThreadPool property set to false or not).

NativeRuntimeEventSourceTest can be used to validate this.

I assume we don't want this in the 8.0 milestone that nobody is looking at anymore, so marked this untriaged.
