util/u_queue: add UTIL_QUEUE_INIT_SCALE_THREADS flag
This flag allow to create a single thread initially, but set
max_thread to the request thread count.
If the queue is full and num_threads is lower than max_threads,
we spawn a new thread to help process the queue faster.
This avoid creating N threads at queue creation time.
