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.
