Revert "Revert "Reland "Remove ContrastAdjust()."""chromium/3253chromium/3252

This reverts commit 978ba20ffd0d2b37bf02b9d86828fa701c0c02fa.

Reason for revert: I now have the new expected files for the

Landing this again and will immediately add a manual pdfium roll to
cl 742061 to unblock the deps roller.
