commit 32426e0c6511485debbf3b7c77e87791b6b3ec93
Author: estade <estade@chromium.org>

Make some updates to extension iconography.

Several related changes in one go:

1. Remove padding from extension search icon in location bar
   (linux, cros, mac). This was causing misalignment between the popup
   icon and the location bar icon, and unintended discrepancies between
   platforms.
2. Make ExtensionIconManager handle all supported scale factors rather
   than just 1x.
3. Remove some obsolete code in the apps page. Apps will always be given
   a default icon, and we never use the small icon codepath any more.
   This also means FaviconWebUIHandler is no longer needed.
