Original change's description:
> [refactoring] Remove the isolate from signatures of ExternalReferences
> 
> In this CL I remove the isolate from signatures of ExternalReference
> accessor functions where the isolate is not used. The uses of the
> isolate were already removed in previous CLs.
> 
> Changes:
> * I split the ExternalReference list in external-reference.h into
> those which need the isolate for initialization and those which do not.
> 
> * I removed the public constructors and replaced them by
>   ExternalReference::Create(). The reason is to separate external
>   creation more clearly from internal creation, because externally
>   created ExternalReferences sometimes need redirection, whereas
>   internally created ExternalReferences are just stored as they are.
>   In addition, by removing the isolate from the signature of the
>   public constructors, they suddenly exactly matched the interal
>   constructor.
> 
> * Replace all uses of the public constructors with
>   ExternalReference::Create().
> 
> * Remove the isolate from all call sites where necessary.
> 
> 
> This is a step towards making WebAssembly compilation independent of
> the isolate.
