SL-16202: Use large WorkQueue size limits for mainloop and General.

Give ThreadPool and WorkQueue the ability to override default
ThreadSafeSchedule capacity.

Instantiate "mainloop" WorkQueue and "General" ThreadPool with very large
capacity because we never want to have to block trying to push to either.
