abfb73f2e7 LibWeb+LibJS: Let JS::Realm::HostDefined objects mark things during GC 
This allows us to mark the HTML::Window from our window environment
settings object.

6f433c8656 LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated 
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.

There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.

9e860d973e LibLocale: Move locale source files to the LibLocale library 
Everything is now setup to create the LibLocale library and link it
where needed.

43a3471298 LibLocale: Move locale source files to the LibLocale folder 
These are still included in LibUnicode, but this updates their location
and the include paths of other files which include them.

6c7b05a0ff LibUnicode+LibJS: Move Unicode::get_available_currencies() to Locale.h 
This is generated by GenerateLocaleData, which will soon be in the
Locale namespace. Move it out of CurrencyCode.h, as that will continue
to live in the Unicode namespace.

63cc2650e3 LibJS: Make Handle<T> more user-friendly 
Allow *handle, !handle, handle.ptr(), assignment from compatible
pointer types, etc. This is in preparation for using Handles in
more generated code.

e34e21367e LibJS: Add GCPtr and NonnullGCPtr 
These are two new smart pointers that are really just raw pointers under
the hood. The initial benefit is all in the names, they allow us to
declare that we're pointing at something in the GC heap.

Later we may also find ways to add debugging logic or static analysis to
these types.

9f661d20f7 LibJS: Allow anonymous functions as default exports 
This requires a special case with names as the default function is
supposed to have a unique name ("*default*" in our case) but when
checked should have name "default".

0fc67ffd62 LibJS: Make indirect bindings of module behave like normal bindings 
Before this we attempted to hack around this by only overriding
has_binding. However this did not cover all cases, for example when
assigning to variables before their declaration it didn't throw.
By using the new find_binding_and_index virtual method we can just
pretend the indirect bindings are real.

Since indirect binding do come from a normal environment we need to
ensure you cannot modify the binding and that properties like mutable
are false as expected by the spec for such an indirect binding.

3b1c3e574f LibJS: Handle empty named export 
This is an export which looks like `export {} from "module"`, and
although it doesn't have any real export entries it should still add
"module" to the required modules to load.

6cedb1b9d9 LibJS: Implement $262.evalScript() according to the given algorithm 
test262's INTERPRETING.md specifies the exact steps for this function,
so let's shuffle some things around and add "spec" comments.

Most importantly this now returns the result of the evaluated script,
which at least one test relies on:

d53a369e7f LibJS: Implement ShadowRealmConstructor::construct() closer to spec 
Defer creation of the global object to Realm::set_global_object(), and
use the newly added set_default_global_bindings() AO as intended.

Linus Groh
040e3abb1d LibJS: Implement SetDefaultGlobalBindings as a standalone function 
Instead of hardcoding all the property definitions in GlobalObject's
initialize() function, make it the standalone AO it is supposed to be
that can then be used by other global objects that don't inherit from
JS::GlobalObject.

e3804e6426 LibJS: Move construction of GlobalObject native functions to Intrinsics 
This will later allow global objects not inheriting from the regular
JS::GlobalObject to pull in these functions without having to implement
them from scratch. The primary use case here is, again, a wrapper-less
HTML::Window in LibWeb :^)

Allocating these upfront now allows us to get rid of two hacks:

- The GlobalObject assigning Intrinsics private members after finishing
  its initialization
- The GlobalObject defining the parseInt and parseFloat properties of
  the NumberConstructor object, as they are supposed to be identical
  with the global functions of the same name

Linus Groh
52543fc771 LibJS+LibWeb: Let Realm store a plain Object for [[GlobalObject]] 
This removes the requirement of having a global object that actually
inherits from JS::GlobalObject, which is now a perfectly valid scenario.

With the upcoming removal of wrapper objects in LibWeb, the HTML::Window
object will inherit from DOM::EventTarget, which means it cannot also
inherit from JS::GlobalObject.
