cmWorkerPool: Set worker thread count separately to Process()

Don't pass the desired worker thread count to the `cmWorkerPool::Process()`
method but set it separately with the new `cmWorkerPool::SetThreadCount`
method.  This allows calling `cmWorkerPool::Process()` repeatedly without
having to pass the thread count every time.
