39ab1a8999 LibJS: Implement ECMA-402 Array.prototype.toLocaleString 
Turns out the only difference between our existing implementation and
the ECMA-402 implementation is we weren't passing the locales and
options list to each element.toLocaleString invocation.

This also adds spec comments to the definition.

58c6a156bf LibCrypto: Fix subtracting two negative SignedBigIntegers 
Currently, we get the following results

    -1 - -2 = -1
    -2 - -1 =  1

Correct would be:

    -1 - -2 =  1
    -2 - -1 = -1

This was already attempted to be fixed in 7ed8970, but that change was
incorrect. This directly translates to LibJS BigInts having the same
incorrect behavior - it even was tested.

a701ed52fc LibJS+LibUnicode: Fully implement currency number formatting 
Currencies are a bit strange; the layout of currency data in the CLDR is
not particularly compatible with what ECMA-402 expects. For example, the
currency format in the "en" and "ar" locales for the Latin script are:

    en: "¤#,##0.00"
    ar: "¤\u00A0#,##0.00"

Note how the "ar" locale has a non-breaking space after the currency
symbol (¤), but "en" does not. This does not mean that this space will
appear in the "ar"-formatted string, nor does it mean that a space won't
appear in the "en"-formatted string. This is a runtime decision based on
the currency display chosen by the user ("$" vs. "USD" vs. "US dollar")
and other rules in the Unicode TR-35 spec.

ECMA-402 shies away from the nuances here with "implementation-defined"
steps. LibUnicode will store the data parsed from the CLDR however it is
presented; making decisions about spacing, etc. will occur at runtime
based on user input.

39e031c4dd LibJS+LibUnicode: Generate all styles of currency localizations 
Currently, LibUnicode is only parsing and generating the "long" style of
currency display names. However, the CLDR contains "short" and "narrow"
forms as well that need to be handled. Parse these, and update LibJS to
actually respect the "style" option provided by the user for displaying
currencies with Intl.DisplayNames.

Note: There are some discrepencies between the engines on how style is
handled. In particular, running:

new Intl.DisplayNames('en', {type:'currency', style:'narrow'}).of('usd')

Gives:

  SpiderMoney: "USD"
  V8: "US Dollar"
  LibJS: "$"

And running:

new Intl.DisplayNames('en', {type:'currency', style:'short'}).of('usd')

Gives:

  SpiderMonkey: "$"
  V8: "US Dollar"
  LibJS: "$"

My best guess is V8 isn't handling style, and just returning the long
form (which is what LibJS did before this commit). And SpiderMoney can
handle some styles, but if they don't have a value for the requested
style, they fall back to the canonicalized code passed into of().

a53542e0a3 LibJS: Clear exception after running each queued Promise job 
It's not what the spec tells us to do. In fact, the spec tells us the
exact opposite:

    9.5 Jobs and Host Operations to Enqueue Jobs
    https://tc39.es/ecma262/#sec-jobs

    A Job is an Abstract Closure with no parameters that initiates an
    ECMAScript computation when no other ECMAScript computation is
    currently in progress.
    ...
    Their implementations must conform to the following requirements:
    - ...
    - The Abstract Closure must return a normal completion, implementing
      its own handling of errors.

However, this turned out to not be true in all cases. More specifically,
the NewPromiseReactionJob AO returns the completion result of calling a
user-provided function (PromiseCapability's [[Resolve]] / [[Reject]]),
which may be an abrupt completion:

    27.2.2.1 NewPromiseReactionJob ( reaction, argument )
    https://tc39.es/ecma262/#sec-newpromisereactionjob

    1. Let job be a new Job Abstract Closure with no parameters that
       captures reaction and argument and performs the following steps
       when called:
       ...
       h. If handlerResult is an abrupt completion, then
          i. Let status be Call(promiseCapability.[[Reject]],
             undefined, « handlerResult.[[Value]] »).
       i. Else,
          i. Let status be Call(promiseCapability.[[Resolve]],
             undefined, « handlerResult.[[Value]] »).
       j. Return Completion(status).

Interestingly, this case is explicitly handled in the HTML spec's
implementation of jobs as microtasks:

    8.1.5.3.3 HostEnqueuePromiseJob(job, realm)
    https://html.spec.whatwg.org/webappapis.html#hostenqueuepromisejob

    2. Queue a microtask on the surrounding agent's event loop to
       perform the following steps:
       ...
       5. If result is an abrupt completion, then report the exception
          given by result.[[Value]].

This is precisely what all the major engines do - but not only in
browsers; the provided code snippet in the test added in this commit
works just fine in Node.js, for example.

https://trac.webkit.org/browser/webkit/trunk/Source/JavaScriptCore/runtime/JSMicrotask.cpp?rev=273718#L94

V8:
https://source.chromium.org/chromium/chromium/src/+/main:v8/src/builtins/promise-abstract-operations.tq;l=481;drc=a760f03a6e99bf4863d8d21c5f7896a74a0a39ea
https://source.chromium.org/chromium/chromium/src/+/main:v8/src/builtins/builtins-microtask-queue-gen.cc;l=331;drc=65c9257f1777731d6d0669598f6fe6fe65fa61d3

This should probably be fixed in the ECMAScript spec to relax the rule
that Jobs may not return an abrupt completion, just like in the HTML
spec. The important bit is that those are not surfaced to user code in
any way.

89523f70cf LibJS: Begin implementing Intl.NumberFormat.prototype.format 
There is quite a lot to be done here so this is just a first pass at
number formatting. Decimal and percent formatting are mostly working,
but only for standard and compact notation (engineering and scientific
notation are not implemented here). Currency formatting is parsed, but
there is more work to be done to handle e.g. using symbols instead of
currency codes ("$" instead of "USD"), and putting spaces around the
currency symbol ("USD 2.00" instead of "USD2.00").
