kinematics: Generic Cartesian kinematics implementation (#6815)
* tests: Added a regression test for generic_cartesian kinematics * kinematics: An intial implementation of generic_cartesian kinematics * generic_cartesian: Refactored kinematics configuration API * generic_cartesian: Use stepper instead of kinematic_stepper in configs * generic_cartesian: Added SET_STEPPER_KINEMATICS command * generic_cartesian: Fixed parsing of section names * docs: Generic Caretsian kinematics documentation and config samples * generic_cartesian: Implemented multi-mcu homing validation * generic_cartesian: Fixed typos in docs, minor fixes * generic_cartesian: Renamed `kinematics` option to `carriages` * generic_cartesian: Moved kinematic_stepper.py file * idex_modes: Internal refactoring of handling dual carriages * stepper: Refactored the code to not store a reference to config object * config: Updated example-generic-cartesian config * generic_cartesian: Restricted SET_STEPPER_CARRIAGES and exported status * idex_modes: Fixed handling stepper kinematics with input shaper enabled * config: Updated configs and tests for SET_DUAL_CARRIAGE new params * generic_cartesian: Avoid inheritance in the added classes Signed-off-by: Dmitry Butyugin <dmbutyugin@google.com>
