Rewrite modeld in python (#29230)

* Added modeld.py (WIP)

* No more VisionIpcBufExtra

* Started work on cython bindings for runmodel

* Got ONNXModel cython bindings mostly working, added ModelFrame bindings

* Got modeld main loop running without model eval

* Move everything into ModelState

* Doesn't crash!

* Moved ModelState into modeld.py

* Added driving_pyx

* Added cython bindings for message generation

* Moved CLContext definition to visionipc.pxd

* *facepalm*

* Move cl_pyx into commonmodel_pyx

* Split out ONNXModel into a subclass of RunModel

* Added snpemodel/thneedmodel bindings

* Removed modeld.cc

* Fixed scons for macOS

* Fixed sconscript

* Added flag for thneedmodel

* paths are now relative to openpilot root dir

* Set cl kernel paths in SConscript

* Set LD_PRELOAD=libthneed.so to fix ioctl interception

* Run from root dir

* A few more fixes

* A few more minor fixes

* Use C update_calibration for now to exactly match refs

* Add nav_instructions input

* Link driving_pyx.pyx with transformations

* Checked python FirstOrderFilter against C++ FirstOrderFilter

* Set process name to fix test_onroad

* Revert changes to onnxmodel.cc

* Fixed bad onnx_runner.py path in onnxmodel.cc

* Import all constants from driving.h

* logging -> cloudlog

* pylint import-error suppressions no longer needed?

* Loop in SConscript

* Added parens

* Bump modeld cpu usage in test_onroad

* Get rid of use_nav

* use config_realtime_process

* error message from ioctl sniffer was messing up pyenv

* cast distance_idx to int

* Removed cloudlog.infos in model.run

* Fixed rebase conflicts

* Clean up driving.pxd/pyx

* Fixed linter error
