Patrick Thier fa1caae9ea Reland "[string] Non-transitioning shared strings"
This is a reland of commit 8ba60b7a8e

Changes to original:
- Weaken DCHECK in MakeThin to allow direct transitions of shared
  strings during deserialization. This is safe as the string to be
  transitioned is freshly created and hasn't escaped the thread yet.
  - To enable this, add has_active_deserializer() to LocalIsolate

- Shared thin string transitions are subject to the same layout changes
  as non-shared thin string transitions, thus treat them equally when
  checking if a map transition is safe.

Original change's description:
> [string] Non-transitioning shared strings
>
> Instead of transitioning shared strings to ThinString on
> internalization, use a forwarding table to the internalized string and
> store the index into the forwarding table in the string's hash field.
>
> This way we don't need to handle concurrent string transitions that
> modify the underlying string data.
>
> During stop-the-world GC, live strings in the forwarding table are
> migrated to regular ThinStrings.
>
