  [LIT] Workaround the 60 processed limit on Windows (#157759)

Python multiprocessing is limited to 60 workers at most:

https://github.com/python/cpython/blob/6bc65c30ff1fd0b581a2c93416496fc720bc442c/Lib/concurrent/futures/process.py#L669-L672

The limit being per thread pool, we can work around it by using multiple
pools on windows when we want to actually use more workers.
