Promise type lookup would need to go through coroutine traits. We could lookup
`coroutine_traits<R>::promise_type` but does not work with `coroutine_traits`
specialized for non-empty parameter list.
The new approach implicitly adds `[[clang::coro_wrapper]]` and
`[[clang::coro_disable_lifetimebound]]` to `get_return_type` found through a
promise lookup.
WDYT ?
