Adding entities twice to a waitset is not allowed, and will introduce subtle bugs. Therefore the rcl_wait function will not explicitly check for duplicated entries in the waitset.

@wjwwood @mjcarroll @alsora This commit adds the check that we agreed on in the last client workgroup meeting

This need to be merged after ros2/rclcpp#2714, as this contains the fix for the two identical guard conditions added by the executor.

Besides the minor request to add a comment, could we have a unit-test for this?
Then the PR would be ready to merge IMO

Added a test case for duplicate timer and duplicate guard condition. I didn't add tests for subscribers and services, as the boilerplate for setup would be a bit much and it would check the identical code path.

LGTM and addresses @alsora's request.

One more CI and we are good to go here?
