This improves and unifies our approach to printing all template arguments. The same approach to printing types is extended to all TemplateArguments: A sugared version is printed in quotes, followed by printing the canonical form, unless they would print the same. Special improvements are done to add more detail to template template arguments. It's planned in a future patch to use this improved TemplateName printer for other places besides TemplateArguments. Note: The sugared/desugared printing does not show up for TemplateNames in tests yet, because we do a poor job of preserving their type sugar. This will be improved in a future patch.
