[mono] Tests failed on windows: System.Reflection.Internal.Tests.AbstractMemoryBlockTests.FileStream/FileStreamUnix

[MaximLipnin]

System.Reflection.Internal.Tests.AbstractMemoryBlockTests.FileStream and System.Reflection.Internal.Tests.AbstractMemoryBlockTests.FileStreamUnix are disabled in Mono's CoreFX.issues_windows.rsp file and after enabling they still fail locally with the following output:

System.Reflection.Internal.Tests.AbstractMemoryBlockTests.FileStream [FAIL]
System.PlatformNotSupportedException : This API is specific to the way in which Windows handles asynchronous I/O, and is not supported on this platform.

These tests will be marked with ActiveIssue in #32592.

@MaximLipnin can you please point me to the right instructions to run this unit test in mono, so I can try to repro the issue?

[MaximLipnin]

@carlossanlop There are some instructions, but actually I do the following steps:

1. in the root folder run build.cmd -subsetcategory mono-libraries -c Release -runtimeconfiguration Release /p:RuntimeFlavor=mono
2. after build completes, run cd src\libraries\System.Reflection.Metadata\tests
3. run dotnet build /t:Test /p:RuntimeFlavor=mono /p:Configuration=Release

ThreadPoolBoundHandle, see #34582

[danmoseley]

Let's just track it all with #34582 and if/when fixing that, they can enable tests from linked issues like this.
