[macOS, UNIX] prefer _SC_PAGESIZE over (partially) deprecated getpagesize() (#1891)
Add a reusable `psutil_getpagesize()` utility common to all UNIXes.
Related to #1885 (`getpagesize()` is deprecated on recent macOS, POSIX.1-2001 and possibly other UNIXes).
The problem emerged on macOS but `getpagesize()` is also used in FreeBSD, NetBSD, OpenBSD and AIX, so it makes sense to do this in one place only, similarly to Windows which also provide a `psutil_getpagesize()` utility.
Follow cPython's `mmapmodule.c` and `resourcemodule.c` lead and rely on `sysconf(_SC_PAGESIZE)` instead, but leave `getpagesize()` in place as last resort/attempt for systems where it's not deprecated and/or they still legitimately rely on it.
Also provide a python wrapper so we can test the return value of this C function against Python's stdlib modules.
