> Remove some dead app host code.
> 
> app_host.exe was removed in r220555. This change removes some dead code
> that was left behind. Specifically:
> - chrome_launcher_support no longer exposes any methods related to the
>   AppHost.
> - Chrome's uninstall prompt no longer has a special case to handle
>   suppressing the "delete your profile" checkbox.
> - Chrome and its installer no longer have a dependency on
>   launcher_support.
> - The installer no longer supports installing items from the webstore.
> - GetUntrustedDataValue no longer has consumers and is gone.
