Note that even though we already implement AvailableTimeZones for Intl,
I kept the existing implementation calling into LibTimeZone directly.

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.
This remained undetected for a long time as HeaderCheck is disabled by
default. This commit makes the following file compile again:
// file: compile_me.cpp
#include <LibJS/Runtime/StringPrototype.h>
// That's it, this was enough to cause a compilation error.
Likewise for most other files touched by this commit.
In a subclass of Cell, we cannot use Cell::vm() before the base Cell
object itself is constructed. Use the Realm's VM instead.
This was caught by UBSAN with vptr sanitation enabled.
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 :^)
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.
This is an editorial change in the Temporal spec.
Now that this is spec'd as either an Object or undefined, we can change
the parameter type from arbitrary JS::Value to JS::Object*.

- 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
This is needed so that the allocated NativeFunction receives the correct
realm, usually forwarded from the Object's initialize() function, rather
than using the current realm.
