This patch allows a user to enable Hwloc on windows.  There are three main changes in here:
1) kmp.h - Move definitions/declarations out of `KMP_OS_WINDOWS` guard (our
   windows implementation of affinity) because they need to be defined when
   `KMP_USE_HWLOC` is on as well.
2) teach `__kmp_set_system_affinity`, `__kmp_get_system_affinity`,
   `__kmp_get_proc_group`, and `__kmp_affinity_bind_thread` how to use hwloc.
3) teach CMake how to include hwloc when building Windows

Another minor change in here is to make sure that anything under `KMP_USE_HWLOC`
is also guarded by `KMP_AFFINITY_SUPPORTED` as well.  This is to prevent Mac
builds from requiring anything from Hwloc.
