Add linker annotation to LazyDebugView to avoid warnings (#39899)

Add linker annotation to LazyDebugView to avoid warnings (#39899)

In reality this is only to get rid of the warnings, the class is never instatiated by the managed code, so the annotation has no effect on including more code.
When in debugger the class is instatiated with the same T of an existing Lazy<T> which has the same annotation, so the T will always fulfill the annotation's requirements.
