Brian Barrett 0e9581d478 build: Move hwloc to a 3rd-party package ...

With Open MPI 5.0, the decision was made to stop building
3rd-party packages, such as Libevent, HWLOC, PMIx, and PRRTE as
MCA components and instead 1) start relying on external libraries
whenever possible and 2) Open MPI builds the 3rd party
libraries (if needed) as independent libraries, rather than
linked into libopen-pal.

This patch moves the hwloc library bundled with Open MPI from a
MCA framework to a stand-alone library built outside of OPAL.  Due
to the amount of code in the MCA base (and its assumptions about
being part of an MCA framework), the framework is left with no
active components.  Any pre-installed version of HWLOC 1.6 or
newer is preferred over the internal version.
