[JSC] op_async_iterator_next DFG should also subscribe promise-watchpoint

Reviewed by Yijia Huang.
We were subscribing promise-watchpoint on op_async_iterator_open but not
in op_async_iterator_next, that's not correct since we may change this
condition in the Generic path of op_async_iterator_open, and still we
may hit the fast path in the op_async_iterator_next. We align much more
to the op_iterator_open / op_iterator_next (did a bit cleanup too). And
now whenever we emit IterationMode::FastAsyncGenerator fast path, we
always subscribe the watchpoint.
