Create a CI pipeline that builds and optionally pushes Docker images
for cross-compilation targets (rk3588) and ROS 2 distributions, with
multi-stage builds for base, toolchain, vendor packages, and ROS 2.
Also ignore diagnostic_remote_logging package in the Lyrical ROS 2
build.
Add ROS_ROOT argument to compose.yaml, update toolchain CMake to search
in ROS_ROOT, and modify final stage of Dockerfiles to copy to ROS_ROOT
instead of TARGET_SYSROOT. Also add support for ROS2 lyrical distro.
