Add bitmaps and skp output to Skia port
This is a first-cut at supporting bitmaps. Also added a --skp option to pdfium_test to generate a Skia picture file. The picture file can be loaded in Skia's SampleApp, debugger, or skiaserver to examine the generated picture. (This also includes fixes suggested in the prior Skia CL. My apologies for fat-fingers abandoning that one.) R=dsinclair@chromium.org, tsepez@chromium.org, dsinclair Review URL: https://codereview.chromium.org/1776313002 .
