Add inline JPEGs.
Allows JPEG data to be copied into the file rather than left in a separate file. This is needed to allow rasterized PDFs to avoid saving image files for each page. See Chromium issue 2524143003 for chromium changes. BUG=534945, 550205, 480628 Review-Url: https://codereview.chromium.org/2529543003
