This adds PyUnstable_Module_SetGIL calls to allow psutil to run with the GIL disabled in the CPython free-threading builds. This also fixes a few thread-safety that could cause problems with the GIL disabled:
The temporary argv C array is no longer global in OpenBSD's proc_cmdline
The maxcpus variable is no longer global in FreeBSD's per_cpu_times.
