Add Delegator support to the Java backend

This Delegator can be used as a wrapper around an interface of the same
type.
The Java Delegator class is gated behind the @JavaDelegator annotation.
The code is only generated when the annotation is present. This saves
code size for all of the interfaces that don't use this.
