  [JSC] Reduce unnecessary function and scope allocations in Promise builtins

Reviewed by Keith Miller.

Inline some of promise handler creation functions and use `let` so that this patch
reduces unnecessary function creation like `newResolveElement`.
We also remove repeated promise capabilities property accesses.
