erts: Use reduction based polling for starved poll-set
When the schedulers never go to sleep (and thus never polls)
it may be that the fds in schedulers poll-sets are never polled.
Before this commit, this was solved by starting a timer when an
overload was detected. This had issues as overloads were not always
detected in time. So this commit reverts to the pre OTP-21 behaviour
so keep a global counter makes that the poll is called when it should.
