…t APIs & introduce C++ SDK tests (#2890) * Part of #2516 (SDK! Not codegen! :)) * Next in the cpp series after #2874 ### What Adds a test dependency to the [Catch2](https://github.com/catchorg/Catch2/) testing framework in order to start testing all the new RecordingStream features added here. C++ tests can be conveniently run via `./rerun_cpp/build_and_run_tests.sh` now! For quick api overview start with the `rerun.h` and `recording_stream.h` headers. Fixes a range of compiler warnings as a consequence of improving some of the CMake setup, more to do there! Adds lots more documentation to RecordingStream as well. Next steps: * Add C++ to ci (linting, running this test suite) * Add roundtrip tests * Add codegen custom code injection * Improve API usability in varous places, including * #2873 * add other tests * serialize unions * serialize datatypes nested in unions, structs and lists * more testing & roundtripping ### Checklist * [x] I have read and agree to [Contributor Guide](https://github.com/rerun-io/rerun/blob/main/CONTRIBUTING.md) and the [Code of Conduct](https://github.com/rerun-io/rerun/blob/main/CODE_OF_CONDUCT.md) * [x] I've included a screenshot or gif (if applicable) * [x] I have tested [demo.rerun.io](https://demo.rerun.io/pr/2890) (if applicable) - [PR Build Summary](https://build.rerun.io/pr/2890) - [Docs preview](https://rerun.io/preview/pr%3Aandreas%2Fcpp-api%2Fbetter-recording-stream/docs) - [Examples preview](https://rerun.io/preview/pr%3Aandreas%2Fcpp-api%2Fbetter-recording-stream/examples)

What
Introduces APIs for component and archetype logging as well as the necessary methods in codegen to do so. A very basic example is included in
main.cpp.Largely unrelated to the rest:
to_arrow_datatypeconstructs/allocates the datatype lazily exactly once (using C++'s crazy localstaticvariable guarantees)Commit by commit review possible.
