feat(ci): Split Linux CI workflow and add container images pipeline
Added a new workflow, container_images.yml, to automate building and pushing CI container images to GitHub Container Registry, ensuring consistent environments for CI runs across Linux distributions. Added a dedicated CI workflow for Linux to streamline testing across multiple CUDA and OS configurations. It reuses the images built from container_images.yml workflow to avoid installing CUDA toolkits every time to save time. Key changes: - Matrix configurations for Ubuntu 22/24, RockyLinux 9 with CUDA 12.8.1 - Dockerfiles updated with required dependencies (clang, CUDA toolchains, etc.) to support bindgen and build examples. - Removed redundant CI steps from `rust.yml` now handled in `ci_linux.yml`
