LibJS+LibWeb: Add JS::Object::inherits(class_name) To allow implementing the DOM class hierarchy in JS bindings, this patch adds an inherits() function that can be used to ask an Object if it inherits from a specific C++ class (by name). The necessary overrides are baked into each Object subclass by the new JS_OBJECT macro, which works similarly to C_OBJECT in LibCore. Thanks to @Dexesttp for suggesting this approach. :^)

LibJS: Move native objects towards two-pass construction To make sure that everything is set up correctly in objects before we start adding properties to them, we split cell allocation into 3 steps: 1. Allocate a cell of appropriate size from the Heap 2. Call the C++ constructor on the cell 3. Call initialize() on the constructed object The job of initialize() is to define all the initial properties. Doing it in a second pass guarantees that the Object has a valid Shape and can find its own GlobalObject.

LibJS: Simplify Cell::initialize() Remove the Interpreter& argument and pass only GlobalObject&. We can find everything we need via the global object anyway.

LibJS: Explicitly pass a "Function& new_target" to Function::construct This allows the proxy handler to pass the proper new.target to construct handlers.

LibJS: Pass GlobalObject& to native functions and property accessors More work towards supporting multiple global objects. Native C++ code now get a GlobalObject& and don't have to ask the Interpreter for it. I've added macros for declaring and defining native callbacks since this was pretty tedious and this makes it easier next time we want to change any of these signatures.
