Constant Descriptors for MethodHandles::classData and classDataAt

Summary

Add Constant Descriptors for MethodHandles::classData and MethodHandles::classDataAt to ConstantDescs.

Problem

MethodHandles::classData and MethodHandles::classDataAt are APIs intended to be used as dynamic constant bootstrap methods, yet they lack Constant Descriptors in ConstantDescs.

Solution

Add constant descriptors for these two methods in ConstantDescs.
