Gold support in PDFium

Extends the PDFium tests to collect images and meta data to be uploaded
to Gold. This feature is triggered by adding the --gold_* flags.

It extends pdfium_test to output the MD5 hash of the underlying pixel
buffer for each page it renders.
That output is then processed by test_runner.py to generate the
gold meta data.

This behavior is modeled after the 'dm' tool in skia. See
https://skia.googlesource.com/skia/+/master/dm/DM.cpp#1090

This should not cause any change in the current behavior of the tests,
it will be trigger once we update the buildbot recipe.
