This macro will be used to mark all coroutine_fn functions.
Right now, it will be used for the newly introduced coroutine_fn, since
we know the callers.
As a TODO, in the future we might want to add this macro to all
corotuine_fn functions, to be sure that they are only called in
coroutines context.
