398c181c79 LibJS: Rename PropertyName to PropertyKey 
Let's use the same name as the spec. :^)

0881f8160f LibJS: Use implicit ThrowCompletionOr<T> constructor where possible 
Luckily this is not very widespread yet as most of it would happen in
the various JS functions instead of AOs.

09536f5f48 LibJS: Fix typo in LHS Object and RHS BigInt loosely equals check 
Step 12 was using `lhs.is_bigint()` instead of `rhs.is_bigint()`,
meaning you got:
```js
1n == Object(1n); // true
Object(1n) == 1n; // false
```

This also adds spec comments to is_loosely_equal.

4d8912a92b LibJS: Convert to_string() to ThrowCompletionOr 
Also update get_function_name() to use ThrowCompletionOr, but this is
not a standard AO and should be refactored out of existence eventually.

44e70d1bc0 LibJS+LibWeb: Let WrapperGenerator deal with legacy_null_to_empty_string 
This concept is not present in ECMAScript, and it bothers me every time
I see it.
It's only used by WrapperGenerator, and even there only relevant in two
places, so let's fully remove it from LibJS and use a simple ternary
expression instead:

    cpp_name = js_name.is_null() && legacy_null_to_empty_string
        ? String::empty()
        : js_name.to_string(global_object);

e67155638c LibJS: Take advantage of Value::Type::Int32 in a bunch of functions 
If a JS::Value has type Int32, we know it's a finite, 32-bit integer.
Use this information to avoid converting it to a double if possible.

38157a6093 LibJS: Move has_constructor() from NativeFunction to FunctionObject 
At a later point this will indicate whether some FunctionObject "has a
[[Construct]] internal method" (separate from the current FunctionObject
call() / construct()), to help with a more spec-compliant implementation
of [[Call]] and [[Construct]].
This means that it is no longer relevant to just NativeFunction.

e37cf73300 LibJS: Rename OrdinaryFunctionObject to ECMAScriptFunctionObject 
The old name is the result of the perhaps somewhat confusingly named
abstract operation OrdinaryFunctionCreate(), which creates an "ordinary
object" (https://tc39.es/ecma262/#ordinary-object) in contrast to an
"exotic object" (https://tc39.es/ecma262/#exotic-object).

However, the term "Ordinary Function" is not used anywhere in the spec,
instead the created object is referred to as an "ECMAScript Function
Object" (https://tc39.es/ecma262/#sec-ecmascript-function-objects), so
let's call it that.

The "ordinary" vs. "exotic" distinction is important because there are
also "Built-in Function Objects", which can be either implemented as
ordinary ECMAScript function objects, or as exotic objects (our
NativeFunction).

More work needs to be done to move a lot of infrastructure to
ECMAScriptFunctionObject in order to make FunctionObject nothing more
than an interface for objects that implement [[Call]] and optionally
[[Construct]].
