Load the first-page xref stream in linearized PDFs.
The header in linearized PDFs contain the first-page xref table, but the
first-page trailer can also reference a first-page xref stream. Now that
CPDF_Parser::LoadLinearizedAllCrossRefV4() can correctly figure out
where that stream is, try loading it.
