e708f1c3a2 LibWeb: Add DOM::ExceptionOr<T> container
Much like AK::Result this carries either a DOM::DOMException or regular
return value and will be used by DOM functions for exceptions that
should be thrown.

8c7d1986b8 LibWeb: Actually construct impl and wrapper in construct() :^)
FooConstructor::construct() is no longer a dummy but now generates
either code to throw an exception (for interfaces without constructor)
or code to construct the wrapper and its impl object.

Constructor overloads are not currenly handled, but that's not something
we need right now anyway. Instead of  regular create() this uses a new
static function create_with_global_object() and passes the WindowObject,
which may be needed - e.g. for XMLHttpRequest, which has an IDL and
JavaScript constructor with no arguments, but needs a DOM::Window in its
create().

ff324fe989 LibWeb: Fix .length of functions generated from IDL
Function::length() is computing the right function length based on its
parameters, but we never called it - instead the *function name length*
was being used, which is obviously wrong. How silly! :^)

29a2aac89a LibWeb: Start implementing <input type=text> using a shadow DOM
Text <input> fields will now generate a basic shadow DOM and attach it
to the input element.

The shadow DOM contains a <div> with some inline style, and an always-
editable text node inside it. Accessing the "value" attribute on such
an input element will get/set the value from that text node.

This is really cool, although not super stable since HTML editing is
not super stable. But it's a start! :^)

5e91e61900 LibWeb: Remove WidgetBox layout node
The approach of attaching sub-widgets to the web view widget was only
ever going to work in single-process mode, and that's not what we're
about anymore, so let's just get rid of WidgetBox so we don't have the
dead-end architecture hanging over us.

The next step here is to re-implement <input type=text> using LibWeb
primitives.

f24b674d7a LibWeb+WebContent: Don't relayout page on every scroll event
The WebContent process was redoing page layout every time you scrolled

ace1b34798 LibWeb: Reset the HTML editing cursor blink cycle on arrow key movement
Also stop exposing the DOM cursor as a mutable reference on Frame,
since event handling code was using that to mess with the text offset
directly. Setting the cursor now always goes through the Frame where
we can reset the blink cycle appropriately.

This makes cursor movement look a lot more natural. :^)

       descendant elements:

       * Whose namespace is the HTML namespace and whose qualified name
         is qualifiedName, in ASCII lowercase.

       * Whose namespace is not the HTML namespace and whose qualified
         name is qualifiedName.

a59b1825ce LibWeb: Basic implementation of global event handlers :^)
Document and HTMLElement now inherit from HTML::GlobalEventHandlers
which allows them to support "onfoo" event handler attributes.

These are assignable both via IDL attributes and content attributes.

Event listeners constructed this way get a special "attribute" flag
on them so we know which one to replace if you reassign them.
This also allows them to coexist with EventTarget.addEventListener().

This is all a bit sloppy, but it works decently for a first cut.
The Window object should also inherit GlobalEventHandlers, but since
we don't generate it from IDL, I haven't taken that step here.

Also this would be a lot nicer if we supported IDL mixins.
