Enables Google Chrome's Safe Browsing Extended Reporting and prevents users from changing this setting.
Extended Reporting sends some system information and page content to Google servers to help detect dangerous apps and sites.
If the setting is set to true, then reports will be created and sent whenever necessary (such as when a security interstitial is shown).
If the setting is set to false, reports will never be sent.
If this policy is set to true or false, the user will not be able to modify the setting.
If this policy is left unset, the user will be able to change the setting and decide whether to send reports or not.
