Generate default AP stream for ink annotation.
This patch generates a default AP stream for ink annotation so that ink annotations without AP stream can be displayed. Also, roll DEPS for testing/corpus to 4119f8e to test ink annotations. BUG=62625 Review-Url: https://codereview.chromium.org/2232553002
