Richard Smith 0a6321f492 Include the arguments for a generic class or interface in diagnostics. (#4511) 
This can lead to us trying and failing to print certain kinds of
constant value, but we can fix that in future changes.

Note that `StringifyType` should probably be substantially refactored.
For this change I'm trying to leave the overall structure relatively
intact, but hopefully this additional formatting support will help guide
future refactorings.
