Plug `System.Type.IsByRefLike` property

[Guillermo-Santos]

What is the usecase for this plug

With the PR #2997 the System.Activator.CreateInstance are plugged to Cosmos, the thing is that ref struct should not be supported by these methods and a NotSupportedException should be throw, but since this property is missing, we do not have any way to check if the type we are working with is a ref struct at runtime.

** Complexity of plug **

Adding a new property to the Vtable and modifying IL2CPU so that said value is set.
