This is a reland of 652e32f9

Original change's description:
> [heap] Make trampoline CodeDataContainers immutable and deduplicate them
>
> Moves all trampoline CodeDataContainers to read-only space, making them
> immutable. Containers with no 'kind specific flags' set or 'promise
> rejection' flag are deduplicated by replacing them with the new canonical
> CodeDataContainers roots.
>
> This saves around 36KB from the snapshot.
