"resources_quick_actions" would be a more standardized naming of this target. 
Matches "resources" and "resources_unit_tests".

quick_action_*.png are only referenced from the Info.plist as are
chromium/Icon-*.png. So I named the target adding icons only referenced from the
Info.plist using the same convention.
