erts: Pass thread progress data where possible
The poll thread does a lot of waking up and then going back to sleep. A large part of the waking up is managing thread progress and a large part of that was using thread specific data to get the thread progress data pointer. With this refactor the tpd is passed to each of the functions which greatly decreases the number of ethr_get_tsd calls which in turn halves the CPU usage of the poller thread in certain scenarios.
