GetFunctionPointerForDelegateTests tests fail with Specified cast is not valid on Browser

[mdh1418]

When running System.Runtime.InteropServices library tests on Browser wasm, two functions fail with Specified cast is not valid:

• GetFunctionPointerForDelegate_MarshalledDelegateNonGeneric_ReturnsExpected
• GetFunctionPointerForDelegate_MarshalledDelegateGeneric_ReturnsExpected

Note

When the tests are not ordered, the suite sometimes fails with the two tests above

[FAIL] System.Runtime.InteropServices.Tests.GetFunctionPointerForDelegateTests.GetFunctionPointerForDelegate_MarshalledDelegateNonGeneric_ReturnsExpected
System.InvalidCastException : Specified cast is not valid.
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
[FAIL] System.Runtime.InteropServices.Tests.GetFunctionPointerForDelegateTests.GetFunctionPointerForDelegate_MarshalledDelegateGeneric_ReturnsExpected
System.InvalidCastException : Specified cast is not valid.
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

And other times, it fails with the six tests from GetDelegateForFunctionPointerTests.cs

These now fail with:
System.PlatformNotSupportedException : No native to managed transitions on this platform.
They cannot be supported without the pinvoke generator.

@vargaz this sounds like net6?
