Add a trackball camera setting (#4764)

* Add a setting that does nothing

* Make the setting actually change the interaction type

* fmt

* Bump `@kittycad/lib` to get the proper camera drag interaction types

* A snapshot a day keeps the bugs away! 📷🐛 (OS: namespace-profile-ubuntu-8-cores)

* Fix camera orientation bugs to support proper camera resetting on "camera orbit" setting change (#5031)

* Add a setting that does nothing

* Make the setting actually change the interaction type

* fmt

* fix: up vector bug fix and camera reset fix. Pushing code to cleanup after debugging

* fix: deleting debugging code

* fix: removing debugging code

* fix: removing debugging console log

* fix: removing console log debugs

* fix: adding comment, restoring code from debugging

* fix: removed lookAt when the orientation is already set from the engine.. I do not think we should be recomputing it?

* fix: this fixes the bug because I was pointing to the getter not the value

* Remove unused imports

* Fix lint for unawaited Promise

* Remove pointless change

* Re-run CI

* A snapshot a day keeps the bugs away! 📷🐛 (OS: namespace-profile-ubuntu-8-cores)

* Re-run CI

* Add display attributes to try to fix cargo test

* Remove backwards compat test case

it's failing because I didn't add cameraOrbit to that type and I don't
want to

* Fix test value (prev user value would have been Spherical before Trackball)
