Subject: [PATCH] Qualify ShutdownCallbackHandle in context.cpp

This upstreams a RoboStack build fix from patch/ros-rolling-rclcpp.win.patch.

Qualifying ShutdownCallbackHandle through the rclcpp namespace avoids dependent-name lookup issues on stricter C++ compilers while keeping the existing callback behavior unchanged.
