kernel/poll: Use a separate thread backpointer for triggered work

Browse source 
The triggered work scheme uses a trick where it overloads the thread
pointer field of the struct poller (which normally stores the ID of
the thread that is blocked in k_poll()) to be able to find the work
queue to which it will submit.

Give it its own pointer field to break this false dependency.
