1. Detect native async function components in dev …

   Adds a development warning to complement the error introduced by facebook#27019.
   
   We can detect and warn about async client components by checking the
   prototype of the function. This won't work for environments where async
   functions are transpiled, but for native async functions, it allows us
   to log an earlier warning during development, including in cases that
   don't trigger the infinite loop guard added in facebook#27019. It does not
   supersede the infinite loop guard, though, because that mechanism also
   prevents the app from crashing.
   
   I also added a warning for calling a hook inside an async function. This
   one fires even during a transition. We could add a corresponding warning
   to Flight, since hooks are not allowed in async Server Components,
   either. (Though in both environments, this is better handled by a
   lint rule.)
