Original change's description:
> Settings: Content settings can now be reset for a group of origins in All Sites.
> 
> Add a three-dot / overflow menu to groups of origins in All Sites. This overflow
> menu allows the entire list of origins to have all their content settings reset
> in one go. This will be preceded with a confirmation dialog.
> 
> Manual test - With #enable-site-settings turned on, change a content setting via
> Page Info > Site settings on both https://permission.site and
> http://permission.site. Navigate to chrome://settings/content/all and see that
> both sites are listed under 'permission.site'. Verify there is an overflow menu
> on this entry and that inside the overflow menu, there is a 'Reset permissions'
> option. Clicking this should bring up a reset permission dialog and confirming
> the dialog should remove this entry from All Sites.
