[AIX][PowerPC] Teach the Threading Library About the Number of Physical Cores on AIX (#67683)
The threading library does not recognize AIX and always returns `-1` for
number of physical cores on AIX. This PR teaches the library to
recognize AIX and obtain the correct value for the number of physical
cores.
