f7bb79d6d1 LibJS: Fast-path ToTemporalTimeZone when the argument is a TimeZone 
This is a normative change in the Temporal spec.

1a84dbcb07 LibJS: Replace GetEpochFromISOParts with GetUTCEpochNanoseconds 
This is an editorial change in the Temporal spec. See:
https://github.com/tc39/proposal-temporal/commit/1b051cc

Note that since Date's implementation of this AO uses Crypto bigints
rather than allocating JS bigints, this change has the fallout of
removing some unused VM parameters and adding an overload of the
IsValidEpochNanoseconds AO for use without a JS::BigInt.

50428ea8d2 LibJS: Move intrinsics to the realm 
Intrinsics, i.e. mostly constructor and prototype objects, but also
things like empty and new object shape now live on a new heap-allocated
JS::Intrinsics object, thus completing the long journey of taking all
the magic away from the global object.
This represents the Realm's [[Intrinsics]] slot in the spec and matches
its existing [[GlobalObject]] / [[GlobalEnv]] slots in terms of
architecture.

In the majority of cases it should now be possibly to fully allocate a
regular object without the global object existing, and in fact that's
what we do now - the realm is allocated before the global object, and
the intrinsics between both :^)

791855deab LibCrypto+LibJS: Remove the create_from methods from BigInteger 
Instead we just use a specific constructor. With this set of
constructors using curly braces for constructing is highly recommended.
As then it will not do too many implicit conversions which could lead to
unexpected loss of data or calling the much slower double constructor.

Also to ensure we don't feed (Un)SignedBigInteger infinities we throw
RangeError earlier for Durations.

b345a0acca LibJS+LibWeb: Reduce use of GlobalObject as an intermediary 
- Prefer VM::current_realm() over GlobalObject::associated_realm()
- Prefer VM::heap() over GlobalObject::heap()
- Prefer Cell::vm() over Cell::global_object()
- Prefer Wrapper::vm() over Wrapper::global_object()
- Inline Realm::global_object() calls used to access intrinsics as they
  will later perform a direct lookup without going through the global
  object

f3117d46dc LibJS: Remove GlobalObject from VM::throw_completion() 
This is a continuation of the previous five commits.

A first big step into the direction of no longer having to pass a realm
(or currently, a global object) trough layers upon layers of AOs!
Unlike the create() APIs we can safely assume that this is only ever
called when a running execution context and therefore current realm
exists. If not, you can always manually allocate the Error and put it in
a Completion :^)

In the spec, throw exceptions implicitly use the current realm's
intrinsics as well: https://tc39.es/ecma262/#sec-throw-an-exception

Note that we don't actually need to implement the AO as we already have
String::formatted() for this, and use unified format strings instead of
zero-padding in individual steps in many cases anyway.

This means we now have to pass a global object and construct a BigInt
object just for the assertion, but oh well. We might want to have an
assertion macro that's optimized away in release builds at a later
point, however.
