Move code to set XML value to CXFA_Node

This CL moves the code to set the XML node data from CJX_Node to
CXFA_Node. The XML node is owned by the XFA node, not the CJX node so it
makes more sense to have the modifications happen there.

This combines the duplicate code in CJX_Node into a single SetToXML
method.
