[bazel_ros2_rules] Handle cmake failures in dependent packages

CMake fails for many packages in the default ros2 humble install,
leaving expected api query results empty. This handles the failure and
surfaces the name of the failing package for investigation.

In order to artificially generate errors, leave `include_packages` empty
in a `ros2_local_repository` instance to pull in all installed packages.
Many will have cmake failures.
