LibWeb: Begin SVG element support This commit starts adding a basic SVG element. Currently, svg elements have support for the width and height properties, as well as the stroke, stroke-width, and fill properties. The only child element supported is the path element, as most other graphical elements are just shorthand for paths.

LibWeb: Remove unecessary dependence on Window from SVG classes These classes only needed Window to get at its realm. Pass a realm directly to construct SCG classes.

#include <LibWeb/Bindings/Intrinsics.h>
LibWeb: Remove Bindings/Forward.h from LibWeb/Forward.h This was resulting in a whole lot of rebuilding whenever a new IDL interface was added. Instead, just directly include the prototype in every C++ file which needs it. While we only really need a forward declaration in each cpp file; including the full prototype header (which itself only includes LibJS/Object.h, which is already transitively brought in by PlatformObject) - it seems like a small price to pay compared to what feels like a full rebuild of LibWeb whenever a new IDL file is added. Given all of these includes are only needed for the ::initialize method, there is probably a smart way of avoiding this problem altogether. I've considered both using some macro trickery or generating these functions somehow instead.

LibWeb: Avoid FlyString lookups when setting IDL interface prototypes This commit introduces a WEB_SET_PROTOTYPE_FOR_INTERFACE macro that caches the interface name in a local static FlyString. This means that we only pay for FlyString-from-literal lookup once per browser lifetime instead of every time the interface is instantiated.
