LibJS: Add a global "Object" constructor This patch adds an "Object" constructor to the global object. The only function it implements so far is Object.getPrototypeOf().

LibJS: Revert Enable EXPLICIT_SYMBOL_EXPORT This reverts commit c14173f651f5a50fdb86beb4b79487454a00f3f6. We should only annotate the minimum number of symbols that external consumers actually use, so I am starting from scratch to do that

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. :^)

JS_OBJECT(ObjectConstructor, NativeFunction);
LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

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.

LibJS: Implement constructor/non-constructor function calls This adds Function::construct() for constructor function calls via `new` keyword. NativeFunction doesn't have constructor behaviour by default, ScriptFunction simply calls call() in construct()

virtual bool has_constructor() const override { return true; }
LibJS: Rework how native functions are called to improve |this| value Native functions now only get the Interpreter& as an argument. They can then extract |this| along with any indexed arguments it wants from it. This forces functions that want |this| to actually deal with calling interpreter.this_value().to_object(), and dealing with the possibility of a non-object |this|. This is still not great but let's keep massaging it forward.
