Port all of Windows Workflow to .NET Core

[terrajobst]

This would depend on #16243

Note: this issue isn't a committment from our side to do so, it merely captures the community request.

@terrajobst Does this mean that there is a decision made to port both System.Xaml and Workflow to .NET Core or it is like in #16243 case simply capturing the community request to do so?

@terrajobst note we already had https://github.com/dotnet/corefx/issues/2394

@terrajobst It would be good to address @4creators' question preemptively on issues you file like this. The answer also isn't clear to me. 😄

[terrajobst]

Thanks for asking. I've clarified in the issue body :-)

Yep, we couldn't find it in the meeting so I just created one. Will close as duplicate of #14862.
