281b0411f2 LibJS: Implement conversion of strings to BigInts according to the spec 
The spec defines a StringToBigInt AO which allows for converting binary,
octal, decimal, and hexadecimal strings to a BigInt. Our conversion was
only allowing for decimal strings.

8bdf6441b1 LibJS: Use u32 for the JS::Shape property count 
We don't need to support more than 2^32 object properties anyway, so
there's no point in using 64-bit property counts.

This small reduction in memory usage makes test-js run ~10% faster on
x86_64 locally.

7a742b17da LibJS: Store ECMAScriptFunctionObject bytecode in an OwnPtr 
Using an Optional was extremely wasteful for function objects that don't
even have a bytecode executable.

This allows ECMAScriptFunctionObject to fit in a smaller size class.

4a51165f5f LibJS: Reorganize JS::Shape members a little bit 
Now that AK::Weakable doesn't have a bunch of padding at the end,
let's move the smaller members of JS::Shape to the end, since there's
nothing to fold into at the start.

1469057033 LibJS: Make JS::Shape smaller by using OwnPtr<HashMap> for transitions 
Many shapes don't have any forward transitions to cache, so we can save
a bunch of memory (and time) by only creating the cache maps when
actually needed.

30fcb07fe8 LibJS: Make JS::Environment smaller by reordering members 
By putting `m_permanently_screwed_by_eval` first, it folds into the
padding at the end of the base class (JS::Cell).

a0253af8c1 LibJS: Generalize Intl.NumberFormat to operate on Value types 
Intl.NumberFormat is meant to format both Number and BigInt types. To
prepare for formatting BigInt types, this generalizes our NumberFormat
implementation to operate on Value instances rather than doubles. All
arithmetic is moved to static helpers that can now be updated with
BigInt semantics.

6b5c882af3 LibJS: Add support for JSON modules 
We now have one supported assertion: 'type' if that is 'json' we attempt

f568939568 LibJS: Implement the import assertions proposal 
The hard part of parsing them in import statements and calls was already
done so this is just removing some check which threw before on
assertions. And filtering the assertions based on the result of a new
host hook.

ac3e42a8de LibJS: Move some Intl.NumberFormat fields into a NumberFormatBase class 
Other Intl objects, such as PluralRules, are to be treated as a
NumberFormat object in some AOs. There's only a handful of fields which
are to be shared between those objects - move them to a base class for
shared reuse.

This also updates the couple of NumberFormat AOs that are meant to
operate on these NumberFormat-like objects.

Alternatively, we could just have objects like PluralRules inherit from
NumberFormat directly. But that messes up the is<NumberFormat> runtime
checks, so this feels safer.

236fd0a2cb LibJS: Change RelativeTimeFormat::number_format to return a reference 
In the one place this will be used, we will know that the NumberFormat
object is non-null. So return a reference, as the AO it is passed off to
also expects a reference.

236025df19 LibJS: Prevent implicit pointer-to-bool conversion in Value constructor 
For example, say you try to create a Value from an Array and forgot to
include LibJS/Runtime/Array.h. This would cause the boolean constructor
to be used instead of a compile error.
