[FIR] Implement deprecation for accessing private operators from public inline function

This only affects delegation operators as well as the for-loop-related
next and hasNext operators.
All the other operators worked correctly before.
In K2, the previously mentioned operator calls will be flagged with a
deprecation error and will become and error in 2.1.
