Update the class template to add the sealed modifier by default

This issue has been moved from a ticket on Developer Community.

In Visual Studio when creating a new class, can we have the sealed modifier included by default?

Posts where the benefit to having sealed classes have been discussed:

• https://www.meziantou.net/performance-benefits-of-sealed-class.htm

Going back and updating the framework is not an option, so the next best thing is possibly to have the template updated to cater for this.

Roslyn doesn't own these templates. Not sure who does. Maybe the sdk? @KathleenDollard ?

Going to move this to the project-system repo, who can redirect it as appropriate.
