(copied from chrome/app/theme/default_[1|2]00_percent/web_ui_close*.png)
(these are the most up-to-date image that we want to use)
Add IDR_CLOSE_DIALOG[_H|_P] to ui_resources.grd

TODO(followup): Remove IDR_WEB_UI_CLOSE* and images, use IDR_CLOSE_DIALOG*.
(that will depend on WIP CL https://codereview.chromium.org/11830002)
