Include nullability annotations

[thomaslevesque]

Is your feature request related to a problem? Please describe. C# 8 introduced nullable reference types, and recent versions of .NET Core / .NET Standard make use of this feature. For instance, String.IsNullOrEmpty accepts a string?. But this is not reflected in the documentation.

Describe the solution you'd like It would be nice to indicate which parameters can be null, using the normal C# syntax (i.e. annotate the type with ?, like for nullable value types)

Describe alternatives you've considered N/A

Additional context N/A

As a bonus, it might be useful to include additional nullability annotations, such as [AllowNull], [NotNullWhen], etc.

@dendeli-msft This should probably be assigned to @mimisasouvanh and possibly @joelmartinez

When will the API docs begin reading the new annotations that have been added to the .NET Core APIs?
