(ann) getAnnotatedReceiverType should not parameterize owner(s) of statically nested classes

[~winterhalter] found that getAnnotatedReceiver type unnecessarily paramterizes owner types of statically nested classes. This causes issues in ByteBuddy and should be fixed.

The output of the following program shows the issue:

  public class Outer<T> {
  
      public static void main(String[] args) throws Exception {
          Method method = Inner.class.getMethod("method", Inner.class);
          AnnotatedType p = method.getAnnotatedParameterTypes()[0];
          AnnotatedType r = method.getAnnotatedReceiverType();
          System.out.println(p.getClass());
          System.out.println(r.getClass());
      }
  
      static class Inner {
          public void method(Inner this, Inner argument) { }
      }
  }
