LibJS: Use FlyString for identifiers This makes variable and property lookups a lot faster since comparing two FlyStrings is O(1).

#include <AK/FlyString.h>
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.

Object::initialize(interpreter, global_object);
LibJS: Simplify and normalize publicly-exposed Object functions Previously, the Object class had many different types of functions for each action. For example: get_by_index, get(PropertyName), get(FlyString). This is a bit verbose, so these methods have been shortened to simply use the PropertyName structure. The methods then internally call _by_index if necessary. Note that the _by_index have been made private to enforce this change. Secondly, a clear distinction has been made between "putting" and "defining" an object property. "Putting" should mean modifying a (potentially) already existing property. This is akin to doing "a.b = 'foo'". This implies two things about put operations: - They will search the prototype chain for setters and call them, if necessary. - If no property exists with a particular key, the put operation should create a new property with the default attributes (configurable, writable, and enumerable). In contrast, "defining" a property should completely overwrite any existing value without calling setters (if that property is configurable, of course). Thus, all of the many JS objects have had any "put" calls changed to "define_property" calls. Additionally, "put_native_function" and "put_native_property" have had their "put" replaced with "define". Finally, "put_own_property" has been made private, as all necessary functionality should be exposed with the put and define_property methods.

JS_DEFINE_NATIVE_FUNCTION(ConsoleObject::clear)
LibJS: Add ConsoleMessage concept A ConsoleMessage is a struct cointaining: * AK::String text; represents the text of the message sent to the console. * ConsoleMessageKind kind; represents the kind of JS `console` function from which the message was sent. Now, Javascript `console` functions only send a ConsoleMessage to the Interpreter's Console instead of printing text directly to stdout. The Console then stores the recived ConsoleMessage in Console::m_messages; the Console does not print to stdout by default. You can set Console::on_new_message to a void(ConsoleMessage&); this function will get call everytime a new message is added to the Console's messages and can be used, for example, to print ConsoleMessages to stdout or to color the output based on the kind of ConsoleMessage. In this patch, I also: * Re-implement all the previously implemented functions in the JavaScript ConsoleObject, as wrappers around Console functions that add new message to the Console. * Implement console.clear() like so: - m_messages get cleared; - a new_message with kind set ConsoleMessageKind::Clear gets added to m_messages, its text is an empty AK::String; * Give credit to linusg in Console.cpp since I used his console.trace() algorithm in Console::trace(). I think that having this abstration will help us in the implementation of a browser console or a JS debugger. We could also add more MetaData to ConsoleMessage, e.g. Object IDs of the arguments passed to console functions in order to make hyperlinks, Timestamps, ecc.; which could be interesting to see. This will also help in implementing a `/bin/js` option to make, for example, return a ConsoleMessageWrapper to console functions instead of undefined. This will be useful to make tests for functions like console.count() and console.countClear(). :^)
