Reviewed by Timothy Hatcher.

This patch keeps track of the content rule list actions that each extension has performed and
exposes them through declarativeNetRequest.getMatchedRules().

These can be filtered on tabId and timeStamp, and are limited to only vending information about
URLs that the extension has access to.

* Source/WebKit/DerivedSources-input.xcfilelist:
* Source/WebKit/DerivedSources.make:
* Source/WebKit/Shared/Extensions/WebExtensionMatchedRuleParameters.h: Added.
* Source/WebKit/Shared/Extensions/WebExtensionMatchedRuleParameters.serialization.in: Added.
* Source/WebKit/UIProcess/Extensions/Cocoa/API/WebExtensionContextAPIDeclarativeNetRequestCocoa.mm:
(WebKit::WebExtensionContext::declarativeNetRequestGetMatchedRules): Iterate over the matched rules and
filter them. Also check to make sure we have permission to access the URLs before vending them.
* Source/WebKit/UIProcess/Extensions/Cocoa/WebExtensionContextCocoa.mm:
(WebKit::WebExtensionContext::unload): Clear the matched rules.
(WebKit::WebExtensionContext::handleContentRuleListNotificationForTab): Increment the blocked resource count
and add the blocked resource to the list of matched rules.
* Source/WebKit/UIProcess/Extensions/Cocoa/WebExtensionControllerCocoa.mm:
(WebKit::WebExtensionController::handleContentRuleListNotification):
* Source/WebKit/UIProcess/Extensions/WebExtensionContext.h:
(WebKit::WebExtensionContext::matchedRules): Keep track of the matched rules.
* Source/WebKit/UIProcess/Extensions/WebExtensionContext.messages.in:
* Source/WebKit/WebKit.xcodeproj/project.pbxproj:
* Source/WebKit/WebProcess/Extensions/API/Cocoa/WebExtensionAPIDeclarativeNetRequestCocoa.mm:
(WebKit::extensionHasPermission): Add a helper method.
(WebKit::toWebAPI): Ditto.
(WebKit::WebExtensionAPIDeclarativeNetRequest::getMatchedRules):
* Tools/TestWebKitAPI/Tests/WebKitCocoa/WKWebExtensionAPIDeclarativeNetRequest.mm:
(TestWebKitAPI::TEST): Add a test that getMatchedRules returns a match that the frame was blocked.
