RFR: 8323698: Class use page does not include extends/implements type arguments [v7]

[Chen Liang]

> Currently in the javadoc tool, the generated class use page does not track the occurrences of a class in the type arguments of the extends or implements list, where they can appear. (See more details on the JBS issue) For example:
> 
> public class One {}
> 
> 
> import java.util.*;
> public class Two extends ArrayList<One> implements Comparator<One> {
> }
> 
> 
> This patch proposes to add new 2 usage categories, "Classes that extend types with arguments of type" and "Classes that implement types with arguments of type" to describe the missing usage scenarios.
> 
> A preview of the new use page with the 2 new categories, generated based on the example above, can be found here: https://cr.openjdk.org/~liach/8323698-javadocuse/doc/class-use/One.html
