[CI] Add paths filters

[christophfroehlich]

as we have in ros2_control repo

[Copilot]

Pull Request Overview

This PR adds path filters to GitHub workflow files to optimize CI/CD execution by only running workflows when relevant files are modified. The changes implement filters similar to those used in the ros2_control repository.

Key changes:

• Added path filters to all GitHub workflow files for both pull_request and push triggers
• Configured filters to trigger on ROS-specific files (.action, .msg, .srv), build files (CMakeLists.txt, package.xml), and the workflow files themselves
• Added repository-specific .repos files to downstream build workflows
