Jeff BaileyandPavel Labath 52fd3ec25a [libc] Define _POSIX_THREADS and support _SC_THREADS in sysconf (#201091) ...

Defined the _POSIX_THREADS macro to 202405L in unistd-macros.h for Linux
to signal POSIX thread support.

Also implemented runtime support for _SC_THREADS in sysconf, returning
_POSIX_THREADS, and added _SC_THREADS and _POSIX_THREADS to the public
unistd.yaml specification.

Added compile-time and runtime tests to verify _POSIX_THREADS definition
and sysconf(_SC_THREADS) behavior. Standardized header comments in
unistd-macros.h to conform to LLVM style.

Assisted-by: Automated tooling, human reviewed.
