multi: multi_wait fixes after #20832
The refactoring in #20832 introduced some inconsistencies between
windows and posix handling, pointed out by reviews. Fix them:

- rename `wait_on_nop` back to `extrawait` as it was called before
- use multi_timeout() to shorten the user supplied timeout for
  both windows/posix in the same way
- remove the extra multi_timeout() check in the posix function
- Add the multi's wakeup socket for monitoring only when there
  are other sockets to poll on or when the caller wants the
  extra waiting time.

Closes #21072
