[iOS] PlatformNotSupportedException in System.Linq.Expressions.Tests.GetDelegateTypeTests test suite

[MaximLipnin]

When trying to enable the interpretation mode for LambdaCompiler on iOS-like targets in #54970, some of the tests from the System.Linq.Expressions.Tests.GetDelegateTypeTests library test suite fail with PlatformNotSupportedException:

System.PlatformNotSupportedException : Operation is not supported on this platform.

   at System.Linq.Expressions.Tests.GetDelegateTypeTests.CantBeFunc(Type[] typeArgs)
   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

The failing tests are:

Setting <IsInterpreting Condition="'$(TargetsiOS)' == 'true' or '$(TargetstvOS)' == 'true' or '$(TargetsMacCatalyst)' == 'true'">true</IsInterpreting> in the test project file helped to address the issue, closing it.
