Implement declarativeNetRequest dynamic and session rules APIs
https://bugs.webkit.org/show_bug.cgi?id=266016
rdar://118476702&;118476774

Reviewed by Timothy Hatcher.

This patch implements:
- declarativeNetRequest.getSessionRules()
- declarativeNetRequest.updateSessionRules()
- declarativeNetRequest.getDynamicRules()
- declarativeNetRequest.updateDynamicRules()

The big difference between these two APIs is that dynamic rules are persisted to disk and will be loaded across
quitting and relaunching the browser. Session rules will go away.

Also, while we are here, fix a typo in an error message and update the localizable strings.

* Source/WebKit/Shared/Extensions/_WKWebExtensionSQLiteStore.h:
* Source/WebKit/Shared/Extensions/_WKWebExtensionSQLiteStore.mm:
(-[_WKWebExtensionSQLiteStore _savepointNameFromUUID:]): Generate a savepoint name based on the UUID.
(-[_WKWebExtensionSQLiteStore createSavepointWithCompletionHandler:]): Create a savepoint in the database.
(-[_WKWebExtensionSQLiteStore commitSavepoint:completionHandler:]): Commit the savepoint to the database.
(-[_WKWebExtensionSQLiteStore rollbackToSavepoint:completionHandler:]): Rollback the database to a given savepoint.
* Source/WebKit/UIProcess/Extensions/Cocoa/API/WebExtensionContextAPIDeclarativeNetRequestCocoa.mm:
(WebKit::WebExtensionContext::declarativeNetRequestDynamicRulesStore): Create and return a _WKWebExtensionDeclarativeNetRequestSQLiteStore for the
dynamic rules. This will only use the in memory database if storage isn't persistent for the extension context.
(WebKit::WebExtensionContext::declarativeNetRequestSessionRulesStore): Create and return a _WKWebExtensionDeclarativeNetRequestSQLiteStore for the
session rules. This will always use the in memory database.
(WebKit::WebExtensionContext::updateDeclarativeNetRequestRulesInStorage): Attempt to perform the given updates to the rules in the database. The flow is:
- Create a savepoint
- Update the rules by removing and adding rules.
    - If this fails, perform a rollback
    - If this succeeds, attempt to load the new rules
        - If this fails, perform a rollback, and attempt to load the old rules
        - If this succeeds, commit the savepoint
(WebKit::WebExtensionContext::declarativeNetRequestGetDynamicRules): Get the rules from the dynamic rules store.
(WebKit::WebExtensionContext::declarativeNetRequestUpdateDynamicRules): Call into updateDeclarativeNetRequestRulesInStorage.
(WebKit::WebExtensionContext::declarativeNetRequestGetSessionRules): Get the rules from the session rules store.
(WebKit::WebExtensionContext::declarativeNetRequestUpdateSessionRules): Call into updateDeclarativeNetRequestRulesInStorage.
* Source/WebKit/UIProcess/Extensions/Cocoa/WebExtensionContextCocoa.mm:
(WebKit::WebExtensionContext::loadDeclarativeNetRequestRules): Chain together loading rules from the various sources, the order is:
- Session rules
- Dynamic rules
- Static rules

(WebKit::WebExtensionAPIDeclarativeNetRequest::updateSessionRules): Call into the UI process after performing argument validation.
(WebKit::WebExtensionAPIDeclarativeNetRequest::getSessionRules): Call into the UI process.
* Tools/TestWebKitAPI/Tests/WebKitCocoa/WKWebExtensionAPIDeclarativeNetRequest.mm:
(TestWebKitAPI::TEST): Add tests for updating dynamic and session rules and verifying that they block content.
