[AA] Render reflection functional types as class types.

Render KFunctionN and KSuspendFunctionN by their class names, rather
than using arrow syntax. These types have additional functionality
beyond purely being able to invoke them (e.g. getting the name of the
referred function), so using arrow syntax throws away that functionality
and may cause breakages in the resulting code.
