The resolve/reject callbacks to PerformPromiseAll is refactored out so
that we can just pass different closures for PerformPromiseAllSettled.

Similarly, a closure to update the value is passed to
Generate_PromiseAllResolveElementClosure so that we can create a
diferrent value in case of Promise.allSettled.
