Replace modelled Dart code comments with Kernel text validation.

Paul, do you want to keep ASCII hierarchies, or the text provides
enough information / easy to read?

I'm fine removing the comments.

File pkg/kernel/test/class_hierarchy_test.dart (right):

https://codereview.chromium.org/2920563002/diff/20001/pkg/kernel/test/class_h...
pkg/kernel/test/class_hierarchy_test.dart:368: class F implements
self::D<core::int, core::bool> {}
