Runtime: Add Diagnostic Command that prints supertypes of a given type

8054888 is an rfe to print superclass hierarchy - either starting with java.lang.Object, or potentially
starting at a specified class or interface and looking to see what inherits from it.

This request is the inverse - which is to start at a given type (class or interface) and find
out what superclasses and superinterface it inherits from, including the hierarchy, so that
if a superinterface is inherited via a superclass rather than directly, that information would
be available.

I would suggest that the information printed would include both class name and defining loader
information.

Ok to wait for feedback on 8054888 or requests from others before implementing this. i.e. to mark jdk10.
