Avoid potential duplicate unique_ptr to CPDF_Document from CPDFXA_Context.
Should FPDFDocumentFromCPDFDocument() be called several times under
XFA, we may WrapUnique() the document several times. So cache a pointer
back from CPDF_Document to CPDFXFA_Context to avoid this.
Because of layering, introduce a placeholder type CPDF_Document::Extension.
This is actually the first step in some larger XFA ownership cleanup, but
makes a nice standalone CL around the one particular issue.
