prevent windows workers from running spsa with large number of params

[Disservin]

Separate issue for #1781

• Problem: Windows cannot handle large command lines See: https://tests.stockfishchess.org/actions?action=&user=mgrabiak&text=The+filename+or+extension+is+too+long

• Windows worker shouldnt be assigned to these tests.

• Windows max length seems to be 32767 characters when used with CreateProcess which I think is probably what the python subprocess library uses, but this needs confirmation.
