  Use a timer to purged old matched rules
https://bugs.webkit.org/show_bug.cgi?id=265950
rdar://118940129

Reviewed by Timothy Hatcher.

When a content rule list notification is saved as a matched rule by an 
extension, start a repeating 5 minute timer to purge
any rules that are older than 5 minutes.

If after the purge there aren't any remaining saved rules, stop the timer.

* Source/WebKit/UIProcess/Extensions/Cocoa/WebExtensionContextCocoa.mm:
(WebKit::WebExtensionContext::handleContentRuleListNotificationForTab): This 
now returns a bool representing if the
notification was saved as a matched rule.
(WebKit::WebExtensionContext::purgeMatchedRulesFromBefore): Iterate over the 
rules and remove any that were from before the given
start time.
* Source/WebKit/UIProcess/Extensions/Cocoa/WebExtensionControllerCocoa.mm:
(WebKit::WebExtensionController::handleContentRuleListNotification): Start a 
timer if the action was saved and there wasn't a timer
started already.
(WebKit::WebExtensionController::purgeOldMatchedRules): Iterate over all of the 
extensions and call purgeMatchedRulesFromBefore.
* Source/WebKit/UIProcess/Extensions/WebExtensionContext.h:
* Source/WebKit/UIProcess/Extensions/WebExtensionController.h:
* 
Source/WebKit/WebProcess/Extensions/API/Cocoa/WebExtensionAPIDeclarativeNetRequestCocoa.mm:
(WebKit::WebExtensionAPIDeclarativeNetRequest::getMatchedRules): Remove an 
extra newline.
