Keep primitive string storage in Utf16String and remove the UTF-8
storage path from PrimitiveString. ASCII strings still use compact
Utf16String ASCII storage, while UTF-16 becomes the only owned
representation.
Build JSON.stringify, Date ISO strings, and Temporal string results with
Utf16StringBuilder when the result is consumed as a JavaScript string.
Keep UTF-8 conversion only at callers that explicitly need bytes outside
LibJS.
Enable -Wexit-time-destructors for all in-tree library targets and
update process-lifetime library statics so they no longer register
exit-time destructors. Long-lived caches, lookup tables, singleton
registries, and generated constants now use NeverDestroyed or leaked
references where the data is intended to live until process exit.
Update LibWeb, LibLine, and the binding generators so regenerated
sources follow the same rule instead of reintroducing destructed
statics.
Same as commit f9fa548d43.
These are String from the outset, so this patch is almost entirely just
changing function parameter types. This will allow us to cache calendar
objects in ICU without invoking any extra allocations.

This is an editorial change in the Temporal proposal. See:

Note: We were actually already using the Temporal definition of this AO
in Intl.DurationFormat, so there's no change needed there.

This also changes the second argument of this AO to not use the alias of
TimeDuration, as that should not be used to refer to epoch nanoseconds.
This was missed in commit 2d9405e5d7.
It was a bit of a semantic mistake too use this alias too eagerly.
Namely, it should not be used to refer to epoch nanoseconds. We now only
use the TimeDuration alias where the spec refers to a value as a time
duration.
This also includes a stubbed Temporal.Duration.prototype.
Until we have re-implemented Temporal.PlainDate/ZonedDateTime, some of
Temporal.Duration.compare (and its invoked AOs) are left unimplemented.
Our Temporal implementation is woefully out of date. The spec has been
so vastly rewritten that it is unfortunately not practical to update our
implementation in-place. Even just removing Temporal objects that were
removed from the spec, or updating any of the simpler remaining objects,
has proven to be a mess in previous attempts.
So, this removes our Temporal implementation. AOs used by other specs
are left intact.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
