LibWeb: Process style sheets in document order Until now we would simply apply stylesheets in the order they finished loading. This patch adds a StyleSheetList object that hangs off of each Document and contains all the style sheets in document order. There's still a lot of work to do for a proper cascade, but at least this makes us consistently wrong every time. :^)

LibWeb: Use "namespace Web::Foo {" since C++20 allows it :^) Thanks @nico for teaching me about this!

LibWeb: Start exposing CSS style sheets to JavaScript :^) This patch adds bindings for the following objects: - StyleSheet - StyleSheetList - CSSStyleSheet You can get to a document's style sheets via Document.styleSheets and iterate through them using StyleSheetList's item() and length(). That's it in terms of functionality at this point, but still neat. :^)

LibWeb: Reimplement the <style> element following the spec We now follow the "update a style block" algorithm from the HTML spec instead of using the ad-hoc CSSLoader mechanism. This necessitated improving our StyleSheet and CSSStyleSheet classes as well, so that's baked into this commit.

LibWeb: Move DOM classes into the Web::DOM namespace LibWeb keeps growing and the Web namespace is filling up fast. Let's put DOM stuff into Web::DOM, just like we already started doing with SVG stuff in Web::SVG.

LibWeb: Use W3C urls for CSSOM spec links https://www.w3.org/TR/cssom/ is the more permanent home of the CSSOM specification's latest version, and is up to date with the draft spec. Also, https://drafts.csswg.org/ has been down multiple times recently which made looking things up a pain.
