The main reason to do this is so that we can compile the demos with the clang static analyzer. As of clang++-14 (what is in Ubuntu 22.04), the default still seems to be C++14, so we need to specify C++17 so that new things in the rclcpp headers work properly.
Further, due to reasons I don't fully understand, I needed to set CMAKE_CXX_STANDARD_REQUIRED in order for clang to really use that version. So set this as well.
