cr23: Update omnibox content settings icons.

The CL hooks up the cr23 icons for content settings. This CL adds new
icons where necessary (using the 20px size). This CL leaves the blocked
redirect icon unchanged since there is no clear cr23 icon at the moment.

Test: Navigate to permission.site. Click on all the permissions.
