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: Move HTML object model stuff into LibWeb/HTML/ Take a hint from SVG and more all the HTML classes into HTML instead of mixing them with the DOM classes.

LibWeb: Move SVG::PathDataParser into its own file and rename it I've chosen the name `AttributeParser` since it parses data from attributes. Rather than duplicate the parsing of numbers and other basic types, let's make use of this existing parsing code for parsing the data for `<line>`, `<polyline>`, etc.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects. Their C++ wrapper classes are removed, and the LibJS garbage collector is now responsible for their lifetimes. There's a fair amount of hacks and band-aids in this patch, and we'll have a lot of cleanup to do after this.

LibWeb: Put most LibWeb GC objects in type-specific heap blocks With this change, we now have ~1200 CellAllocators across both LibJS and LibWeb in a normal WebContent instance. This gives us a minimum heap size of 4.7 MiB in the scenario where we only have one cell allocated per type. Of course, in practice there will be many more of each type, so the effective overhead is quite a bit smaller than that in practice. I left a few types unconverted to this mechanism because I got tired of doing this. :^)

LibWeb: Port Element::attribute_changed from DeprecatedString to String Which as you would expect has a bunch of fallout, but also results in a whole lot of awkward conversions falling away.

LibWeb: Update SVG `get_path()` API to take a viewport size This will allow resolving paths that use sizes that are relative to the viewport. This necessarily removes the on element caching, which has been redundant for a while as computed paths are stored on the paintable.
