Fix wrong page count returned in FPDF_GetPageCount() for dynamic XFA files
In FPDF_GetPageCount(), 'document' is converted to a non-XFA
document pointer (CPDF_Document*). So it only returns non-XFA
or static XFA page count. If XFA files include dynamic XFA fields
on some pages, the returned value doesn't reflect these pages.
