Revert yieldy behavior for non-use Suspense (in Flight, too)

Same as #25537 but for Flight.

I was going to wait to do this later because the temporary
implementation of async components uses some of the same code that
non-used wakables do, but it's not so bad. I just had to inline one bit
of code, which we'll remove when we unify the implementation with `use`.
