[mono] Tests failed on windows: System.Runtime.InteropServices.Tests

[MaximLipnin]

A lot of System.Runtime.InteropServices.Tests tests fail on windows.

The example of CI output :

System.Runtime.InteropServices.Tests.ReleaseComObjectTests.ReleaseComObject_NonComObject_ThrowsArgumentException [FAIL]
    Assert.Throws() Failure
    Expected: typeof(System.ArgumentException)
    Actual:   typeof(System.PlatformNotSupportedException): COM Interop is not supported on this platform.

cant resolve internal call to "System.Runtime.InteropServices.Tests.Common.ComImportObject::.ctor" (tested without signature also)

Your mono runtime and class libraries are out of sync.
The out of sync library is: C:\h\w\9EB608BF\w\AA6F0948\e\System.Runtime.InteropServices.Tests.dll

When you update one from git you need to update, compile and install
the other too.
Do not report this as a bug unless you're sure you have updated correctly:
you probably have a broken mono install.
If you see other errors or faults after this message they are probably related
and you need to fix your mono install first.

The failing tests will be mark with ActiveIssue in #32592.

@MaximLipnin is COM Interop is not supported on this platform expected - doesn't Mono support COM interop?

[MaximLipnin]

@danmosemsft Thanks for taking a look. I'm not sure about Mono's support in this case. What I can do in such cases is to track down possible reason, but because the number of disabled tests/classes/namespaces that I need to check within my work for removing rsp files is quite big, it can take long time to investigate. So I just file a tracking issue which someone with broader knowledge can take a look at and decide what to do.
