Fix page movement handling in XFA-based PDFs

Fixes issues with FPDF_MovePages() when used on XFA-enabled PDFs by
adding separate logic for XFA extensions. This ensures consistent page
movement behavior between standard and XFA-based documents.

The patch refines handling of XFA objects during page move operations to
preserve form data and structure. Tests for both page movement and
insertion in XFA PDFs have been added and verified.

Original patch and code contributions by Stefan Ziegler, with further
modifications and testing to ensure stability and backward
compatibility.
