Use counter instead of vector of futures in `_parallel_run` (pytorch#…

…36159) (pytorch#36334)

Summary:
This should be faster than allocating one mutex, flag and conditional variable per task.

Using `std::atomic<size_t>` to count remaing tasks is not sufficient,
because modification of remaining counter and signalling conditional variable must happen atomically,
otherwise `wait()` might get invoked after `notify_one()` was called.
