Since these are being used specifically for Ash, so all six of these new icons
should instead live in ash/resources/vector_icons (this is a somewhat recent
change, and I have updated the documentation to explain:
https://www.chromium.org/developers/how-tos/vectorized-icons-in-native-chrome-ui)

Also please name these system_menu_emoticon (or ime_menu_emoticon if you wish)
to stay consistent with the other icons that are on a 20x20 pixel grid.

Done. Thanks for the doc.
