[TaskScheduler] Introduce TrackedRef and replace SchedulerWorkerPoolImpl::live_workers_count with it

See tracked_ref.h for details.

This CL is intended to mostly be a no-op. The important bit is introducing TrackedRefs
so they can be used in https://chromium-review.googlesource.com/c/chromium/src/+/1013597
to fix crbug.com/827615 once and for all

Also clean up |join_for_testing_returned_| which only needs to be a bool in DCHECK_IS_ON() builds.
