--- fixes: - | Refactor templates in lf-c-cpp-jobs.yaml with common anchor/alias lf_cmake_common to reduce redundant configuration. This includes gerrit-cmake-sonar, github-cmake-sonar, gerrit-cmake-sonarqube, github-cmake-sonarqube, gerrit-cmake-stage, github-cmake-stage, gerrit-cmake-verify and github-cmake-verify. No functional change. Document maven settings parameters in g*t-cmake-stage templates.
