c++, coroutines: Only allow void get_return_object if the ramp is void [PR100476].
Require that the value returned by get_return_object is convertible to
the ramp return. This means that the only time we allow a void
get_return_object, is when the ramp is also a void function.
We diagnose this early to allow us to exit the ramp build if the return
values are incompatible.
