CMake 3.27 deprecates compatibility with CMake < 3.5. Update tests that do not cover older interfaces to avoid the deprecation warning. Follow the pattern from: * commit7b07ccdd2b(Tests/*Only: Update cmake_minimum_required versions, 2020-06-15, v3.19.0-rc1~629^2~1) * commit72e7c45e98(Tests: Bump CMake minimum required in tests to 2.8.12, 2020-12-22, v3.20.0-rc1~224^2) * commitf6b4db365a(Tests: bump cmake_minimum_required version to 2.8.12, 2021-04-04, v3.21.0-rc1~372^2) Also remove explicit `cmake_policy` settings made redundant by the version.
