Replace NotImplementedException with NotSupportedException

Fixes #20961

> You might choose to throw a NotImplementedException exception in properties or methods in your own types when the that member is still in development and will only later be implemented in production code. In other words, a NotImplementedException exception should be synonymous with "still in development."

I left one NotImplementedException in Migration.cs, because it really is there for when the application hasn't implemented Down yet, but tries to do a Down.
