LibWeb: Start adding support for the <iframe> element! :^) This patch introduces a bunch of things: - Subframes (Web::Frame::create_subframe()) - HTMLIFrameElement (loads and owns the hosted Web::Frame) - LayoutFrame (layout and rendering of the hosted frame) There's still a huge number of things missing, like scrolling, overflow handling, event handling, scripting, etc. But we can make a little iframe in a document and it actually renders another document there. I think that's pretty cool! :^)

LibWeb: Add a FrameHostElement for frame/iframe common functionality A FrameHostElement is an HTML element (<frame> or <iframe>) that may have a content frame that participates in the frame tree. This basically just moves code from <iframe> to a separate base class so we can share it with <frame> once we implement <frame>.

LibWeb: Add a whole bunch of HTML DOM bindings Note that these aren't full implementations of the bindings. This mostly implements the low hanging fruit (namely, basic reflections) There are some attributes that should be USVString instead of DOMString. However, USVString is a slightly different definition of DOMString, so it should suffice for now.

LibWeb: Compute element style in Layout::TreeBuilder Instead of making each Layout::Node compute style for itself, we now compute it in TreeBuilder before even calling create_layout_node(). For non-element DOM nodes, we create the style and layout tree node in TreeBuilder. This allows us to move create_layout_node() from DOM::Node to DOM::Element.

LibWeb: Make the node mutation event functions spec compliant This particularly affects the insertion steps and the removed steps. The insertion steps no longer take into the parent that the node was inserted to, as per the spec. Due to this, I have renamed the function from "inserted_into" to simply "inserted". None of the users of the insertion steps was using it anyway. The removed steps now take a pointer to the old parent instead of a reference. This is because it is optional according to the spec and old parent is null when running the removal steps for the descendants of a node that just got removed. This commit does not affect HTMLScriptElement as there is a bit more to that, which is better suited for a separate commit. Also adds in the adopted steps as they will be used later.

LibWeb: Move automatic browsing context creation to HTMLIFrameElement We will soon have two DOM nodes which contain nested browsing contexts: HTMLIFrameElement and HTMLObjectElement. Only HTMLIFrameElement should have its nested context created automatically upon insertion, so move the invocation of that logic to HTMLIFrameElement.

LibWeb: Delay sub-Frame construction until host Document is attached While we're parsing a new document, we don't have a Frame to grab at. We now use the Node::document_did_attach_to_frame() notification hook to delay subframe construction. With this, subframes now always have a valid reference to their enclosing main frame.
