Add yet another pixel test for an edited PDF that regressed

While fixing crbug.com/40932618, the fix caused yet another regression
for other edited PDFs. Add a test case for the regression, where there
are multiple cross reference tables linked together using the /Prev
entries in trailers. There are also /XRefStm entries that are
effectively useless and dead ends when traversed.

As with other regression tests for edited PDFs:

- The file is yet another handcrafted variant of rectangles.pdf.
- The file uses the same fake objects technique as
  testing/resources/pixel/bug_2123.pdf to deliberately confuse
  CPDF_Parser::RebuildCrossRef().
- The test case starts out suppressed.
