UI needs to distinguish the cases when a channel is shimmed and is unshimmed. When a channel is unshimmed, we unblock the channel and simply treat the channel as a non-tracking channel. When a channel is shimmed, although the channel is unblocked by URLCLassifier, we still want to show it in the UI. For this case, URLClassifier will notify a content blocking event when a channel is unblocked. This patch adds a new allow API, so the caller can use unblock() or allow() depending upon the case it requires. Differential Revision: https://phabricator.services.mozilla.com/D93271
