winrt: Refactor timer callbacks

With the previous solution, a thread pool timer callback fired
in the same thread as the dispatcher. Now that timers can be called
from the base thread pool, callbacks can come from alternate threads and
so the associated event dispatcher must be tracked. This change refactors
how timer info objects are created and tracked so that they can be
properly created/destroyed/queued inside the timer callbacks.

All QTimer tests pass.
