[iOS] PlatformNotSupportedException in System.Linq.Expressions.Tests.GetDelegateTypeTests test suite #55068

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.Compiler.DelegateHelpers.MakeNewCustomDelegate(Type[] types)
   at System.Linq.Expressions.Compiler.DelegateHelpers.MakeNewDelegate(Type[] types)
   at System.Linq.Expressions.Compiler.DelegateHelpers.MakeDelegateType(Type[] types)
   at System.Linq.Expressions.Expression.GetDelegateType(Type[] typeArgs)
   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:

• System.Linq.Expressions.Tests.GetDelegateTypeTests.CantBeFunc(typeArgs: [typeof(string), typeof(System.Double*), typeof(int)])
• System.Linq.Expressions.Tests.GetDelegateTypeTests.CantBeAction(typeArgs: [typeof(System.Int32*)])
