Add classification support for the nullable suppression operator

[jasonmalinowski]

I'd love it if this was a separate classification type so I could make uses of it red. I'd propose the default is still to have the standard color since people may not like that.

This was discussed and agreed that people indeed may want to flag this since it's a special and potential evil operator. We'll offer a special classification option but by default it won't do anything.

Closing out. if we want to do this, we should make an actual work item with a real milestone.
