This function was only needed for extrasUtils. Since it was simply
calling a builtin function, just expose that builtin instead. This
requires an arguments adapter frame for the builtin. As a drive-by
fix, also added an arguments adapter for the extrasUtils.resolvePromise
(and a regression test).

Other cleanup: removed unused native context slot for PROMISE_SET_AND_CREATE.
