Rename CPDFXFA_Document to CPDFXFA_Context

Rename CPDFXFA_Document to CPDFXFA_Context

The CPDFXFA_Document class isn't a document, it contains documents. Renamed
to make the purpose a bit clearer.

PTAL.

I think this makes more sense as a name. I'd like to try to get a CPDF_Context
super-class in there and replace UnderlyingDocumentType with CPDF_Context and
give it a GetPDFDocument() call.

WDYT?
