Normally Cyberpunk 2077 spawns #cpu_threads of dispatcher threads. However with Freebsd, since create_logical_proc_info was a stub, the game would instead spawn a single dispatcher thread, causing the game to just crawl.
Working around the issue by adding a barebone implementation of create_logical_proc_info for FreeBSD so that the game would at least get a thread count through ntdll.
