LibJS: Start implementing Date :^) This adds: - A global Date object (with `length` property and `now` function) - The Date constructor (no arguments yet) - The Date prototype (with `get*` functions)

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+LibWeb: Replace GlobalObject with Realm in object constructors No functional changes - we can still very easily get to the global object via `Realm::global_object()`. This is in preparation of moving the intrinsics to the realm and no longer having to pass a global object when allocating any object. In a few (now, and many more in subsequent commits) places we get a realm using `GlobalObject::associated_realm()`, this is intended to be temporary. For example, create() functions will later receive the same treatment and are passed a realm instead of a global object.

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

Libraries: Use default constructors/destructors in LibJS https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#cother-other-default-operation-rules "The compiler is more likely to get the default semantics right and you cannot implement these functions better than the compiler."

LibJS: Convert NativeFunction::{call,construct}() to ThrowCompletionOr Both at the same time because many of them call construct() in call() and I'm not keen on adding a bunch of temporary plumbing to turn exceptions into throw completions. Also changes the return value of construct() to Object* instead of Value as it always needs to return an object; allowing an arbitrary Value is a massive foot gun.
