LibWeb: Implement loading a favicon in absence of a <link> icon element

Browse source 
For example, serenityos.org does not contain a <link rel="icon"> element
to indicate its favicon. Before navigables, we implemented attempting to
load a fallback favicon in a rather ad-hoc manner. This implements the
full spec steps to do so after the HTML document is parsed.
