Add Constant Descriptors for DirectMethodHandleDesc of MethodHandles::classData and classDataAt in ConstantDescs. This facilitates easier access of class data via condy in Classfile API-generated bytecode. Most other constant bootstrap methods provided in the JDK, notably from `ConstantBootstraps`, already have constant descriptors in ConstantDescs.
