remove `gnc.escape`.

The original intention of `gnc.escape` was to tell `gnc.await` not to handle generator functions that have gone through this function. In fact, no one uses this function at all, because there would never be a situation where a normal function returns a generator function when `genCoroutine` is needed. Now that `gnc.await` has been removed from the project, there is even less need for `gnc.escape` to exist.
