WebContent: Added IPC calls for initializing JS console and sending input

WebContent: Create a separate realm for JS console input This allows us to expose extra functions and properties to the console, such as `$0`, without them being available to website scripts. `ConsoleEnvironmentSettingsObject` is basically a stub, since we require an `EnvironmentSettingsObject` but it has abstract methods.

Ladybird+WebContent: Update IPC calls to handle multiple traversables The IPC layer between chromes and LibWeb now understands that multiple top level traversables can live in each WebContent process. This largely mechanical change adds a billion page_id/page_index arguments to make sure that pages that end up opening new WebViews through mechanisms like window.open() still work properly with those extra windows.

LibJS+WebContent+Browser+js: Implement console.group() methods This implements: - console.group() - console.groupCollapsed() - console.groupEnd() In the Browser, we use `<details>` for the groups, which is not actually implemented yet, so groups are always open. In the REPL, groups are non-interactive, but still indent any output. This looks weird since the console prompt and return values remain on the far left, but this matches what Node does so it's probably fine. :^) I expect `console.group()` is not used much outside of browsers.

Browser+WebContent+LibJS: Support `%c` specifiers in Console.log() ...and the other Console methods. This lets you apply styling to a log message or any other text that passes through the Console `Formatter` operation. We store the CSS on the ConsoleClient instead of passing it along with the rest of the message, since I couldn't figure out a nice way of doing that, as Formatter has to return JS::Values. This way isn't nice, and has a risk of forgetting to clear the style and having it apply to subsequent messages, but it works. This is only supported in the Browser for now. REPL support would require parsing the CSS and figuring out the relevant ANSI codes. We also don't filter this styling at all, so you can `position: absolute` and `transform: translate(...)` all you want, which is less than ideal.

WebContent: Implement ConsoleGlobalObject which proxies to WindowObject ConsoleGlobalObject is used as the global object when running javascript from the Browser console. This lets us implement console-only functions and variables (like `$0`) without exposing them to webpage content. It passes other calls over to the usual WindowObject so any code that would have worked in the webpage will still work in the console. :^)
