This upstreams the thread-linking portion of RoboStack downstream patch `patch/ros-rolling-rcutils.patch`. rcutils uses pthread-backed functionality, for example pthread_once in src/base64.c and the pthread fallback path for thread-local storage on older iOS. Find and link the CMake Threads target explicitly, and export it for downstream consumers, instead of relying on platform-specific implicit pthread linkage.

This is part of an effort to contribute RoboStack downstream patches back upstream.
Origin:
patch/ros-rolling-rcutils.patch, authored by Daisuke Nishimatsu.This extracts the thread-linking portion of the downstream patch.
rcutilsuses pthread-backed functionality, for examplepthread_onceinsrc/base64.cand the pthread fallback path for thread-local storage on older iOS. Finding and linking CMake'sThreads::Threadstarget makes that dependency explicit, and exportingThreadsmakes the package metadata more conservative for downstream consumers.
