[OPENMP] omp_get_proc_id uses sched_getcpu fallback on FreeBSD 13.1 and above

[jlpeyton]

Instead of a KMP_OS_FREEBSD_SCHED guard in kmp_platform.h, can you make a KMP_HAVE_SCHED_GETCPU guard defined as:

#define KMP_HAVE_SCHED_GETCPU (KMP_OS_LINUX || (KMP_OS_FREEBSD && __FreeBSD_version >= 1301000))

And put this somewhere in kmp_os.h where some of the other features are defined (like attributes, KMP_HAVE_MWAIT, etc.). You can then use it in ompt-general.cpp

[devnexen]

sure why not will do it.
