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.
