Add a test PDF with an empty xref table.

Test loading it with various document loading functions to make sure
they behave consistently with regards to whether the document needs to
have its xref table rebuilt.

Right now, it does require a rebuild. Most PDF viewers, along with
pdfium_test, are fine with the empty xref table. pdfium_test uses a
separate FPDF_FILEACCESS implementation from pdfium_embeddertests, so
pdfium_test actually behaves inconsistently with this test.

It is preferable to avoid rebuilding the xref table. Rebuilding requires
more work and may not always rebuild correctly. There will be a
follow-up to skip the rebuild.
