LibWebView+UI: Migrate Ladybird's command line flags to LibWebView Currently, if we want to add a new e.g. WebContent command line option, we have to add it to all of Qt, AppKit, and headless-browser. (Or worse, we only add it to one of these, and we have feature disparity). To prevent this, this moves command line flags to WebView::Application. The flags are assigned to ChromeOptions and WebContentOptions structs. Each chrome can still add its platform-specific options; for example, the Qt chrome has a flag to enable Qt networking. There should be no behavior change here, other than that AppKit will now support command line flags that were previously only supported by Qt.

LibWebView+WebContent: Monitor for system time zone changes This creates a TimeZoneWatcher in the UI process to inform all open WebContent processes when the time zone changes. The WebContent process will clear its time zone cache to retrieve a fresh zone the next time it is asked for one.

LibWebView: Add facilities to ask the user for a download directory If the Downloads directory exists, we will use it (note that this will respect the XDG_DOWNLOAD_DIR environment variable). Otherwise, we will ask the UI layer to retrieve a download directory from the user. This directory is not saved, so it will be re-prompted every time. Once a proper settings UI is complete, we will of course integrate with that for persistent settings.

LibWebView+UI: Generate the application debug menu By migrating the debug menu to LibWebView, the AppKit and Qt UIs are now in sync - the AppKit UI was previously missing some actions. Further, this inadvertently fixes bugs around applying debug settings to new web views, especially across site-isolated processes. We were previously not applying settings appropriately; this now "just works" in the LibWebView infra.

LibWebView+UI: Move the database and cookie jar to WebView::Application The main motivator here was noticing that --disable-sql-database did not work with AppKit. Rather than re-implementing this there, move ownership of these classes to WebView::Application, so that each UI does not need to individually worry about it.

LibWebView+WebDriver+UI: Migrate headless browsing to main Ladybird exe We currently create a separate headless-browser application to serve two purposes: 1. Allow headless browsing to take a screenshot of a page or print its layout tree / internal text. 2. Run the LibWeb test framework. This patch migrates (1) to the main Ladybird executable. The --headless flag enables this mode. This matches the behavior of other browsers, and means we have one less executable to ship at distribution time. We want to avoid creating too many AppKit / Qt facilities in headless mode. So this involves some shuffling of application init to ensure we don't create them until after we've parsed the command line arguments. Namely, we avoid creating the NSApp in AppKit and QCoreApplication in Qt. Doing so also requires that we don't create the application event loop until we've parsed the command line as well, because the loop we create depends on whether we're creating those UI facilities.

LibWebView+UI: Generate application context menus This migrates all duplicated context menus from the UIs to LibWebView. The context menu actions are now largely handled directly in LibWebView, with some UI-specific callbacks added to display e.g. confirmation dialogs. Actions that only ever apply to a specific web view are stored on the ViewImplementation itself. Actions that need to be dynamically applied to the active web view are stored on the Application.

The --headless flag enables this mode. This matches the behavior of other browsers, and means we have one less executable to ship at distribution time. We want to avoid creating too many AppKit / Qt facilities in headless mode. So this involves some shuffling of application init to ensure we don't create them until after we've parsed the command line arguments. Namely, we avoid creating the NSApp in AppKit and QCoreApplication in Qt. Doing so also requires that we don't create the application event loop until we've parsed the command line as well, because the loop we create depends on whether we're creating those UI facilities.

LibWebView: Create a dedicated settings observer for the Application We had a bit of an awkward setup where we want the Application to be a SettingsObserver, but neither the Settings object nor the Application itself was fully initialized by the time the observer was created. So we invented a deferred observer initializer specifically for the Application. Instead, let's just create a dedicated observer subclass that is owned by the Application. We can then create it once we have the singleton Application appropriately set up.

LibWebView+WebDriver+UI: Migrate headless browsing to main Ladybird exe We currently create a separate headless-browser application to serve two purposes: 1. Allow headless browsing to take a screenshot of a page or print its layout tree / internal text. 2. Run the LibWeb test framework. This patch migrates (1) to the main Ladybird executable. The --headless flag enables this mode. This matches the behavior of other browsers, and means we have one less executable to ship at distribution time. We want to avoid creating too many AppKit / Qt facilities in headless mode. So this involves some shuffling of application init to ensure we don't create them until after we've parsed the command line arguments. Namely, we avoid creating the NSApp in AppKit and QCoreApplication in Qt. Doing so also requires that we don't create the application event loop until we've parsed the command line as well, because the loop we create depends on whether we're creating those UI facilities.

Further, this inadvertently fixes bugs around applying debug settings to new web views, especially across site-isolated processes. We were previously not applying settings appropriately; this now "just works" in the LibWebView infra.
