5e9a11b13d LibWebView: Respect autocomplete response Content-Encoding headers
For example, Google uses ISO-8859-1 encoding. This patch allows us to
decode such responses, falling back to UTF-8 if a Content-Type was not
specified or could not be parsed. We should also now handle if decoding
fails, rather than crashing inside JsonParser.

5d2e6ffe30 LibWebView: Add autocomplete settings to about:settings
This implements an autocomplete engine inside LibWebView, to replace the
engine currently used by Qt. Whereas Qt uses the Qt Network framework to
perform autocomplete requests, LibWebView uses RequestServer. This moves
downloading this untrusted data out of the browser process.

This patch only implements the persisted settings and their UI. It does
not integrate this engine into the browser UI.

41aeb9e63a LibWeb+LibWebView+WebContent: Introduce a WebUI framework
When we build internal pages (e.g. about:settings), there is currently
quite a lot of boilerplate needed to communicate between the browser and
the page. This includes creating IDL for the page and the IPC for every
message sent between the processes.

These internal pages are also special in that they have privileged
access to and control over the browser process.

The framework introduced here serves to ease the setup of new internal
pages and to reduce the access that WebContent processes have to the
browser process. WebUI pages can send requests to the browser process
via a `ladybird.sendMessage` API. Responses from the browser are passed
through a WebUIMessage event. So, for example, an internal page may:

    ladybird.sendMessage("getDataFor", { id: 123 });

    document.addEventListener("WebUIMessage", event => {
        if (event.name === "gotData") {
            console.assert(event.data.id === 123);
        }
    });

To handle these messages, we set up a new IPC connection between the
browser and WebContent processes. This connection is torn down when
the user navigates away from the internal page.

e084a86861 LibWebView+UI: Introduce a persistent settings object
This adds a WebView::Settings class to own persistent browser settings.
In this first pass, it now owns the new tab page URL and search engine
settings.

For simplicitly, we currently use a JSON format for these settings. They
are stored alongside the cookie database. As of this commit, the saved
JSON will have the form:

    {
        "newTabPageURL": "about:blank",
        "searchEngine": {
            "name": "Google"
        }
    }

(The search engine is an object to allow room for a future patch to
implement custom search engine URLs.)

For Qt, this replaces the management of these particular settings in the
Qt settings UI. We will have an internal browser page to control these
settings instead. In the future, we will want to port all settings to
this new class. We will also want to allow UI-specific settings (such as
whether the hamburger menu is displayed in Qt).

daca9f5995 LibDevTools+LibWebView+WebContent: Selectively fetch DOM node properties
When we inspect a DOM node, we currently serialize many properties for
that node, including its layout, computed style, used fonts, etc. Now
that we aren't piggy-backing on the Inspector interface, we can instead
only serialize the specific information required by DevTools.

5810c8073e LibWeb+LibWebView+WebContent: Begin implementing simple site islotation
Site isolation is a common technique to reduce the chance that malicious
sites can access data from other sites. When the user navigates, we now
check if the target site is the same as the current site. If not, we
instruct the UI to perform the navigation in a new WebContent process.

The phrase "site" here is defined as the public suffix of the URL plus
one level. This means that navigating from "www.example.com" to
"sub.example.com" remains in the same process.

There's plenty of room for optimization around this. For example, we can
create a spare WebContent process ahead of time to hot-swap the target
site. We can also create a policy to keep the navigated-from process
around, in case the user quickly navigates back.

DevTools server about the state of the application.

a central location to avoid this.
