New Cam simulator based on low level OpenGL functions (faster and more precise) (#13884)

* Initial opengl test window

* added core files

* some fixes for code comparability with other platforms

* more compatibility cleanup

* add missing opengl libraries

* Basic simulation window works!

* try using different define

* fix wrapper for better compatibility

* Gui is now operational

* Finally SIM works on actual freecad models

* support drill commands

* cleanup python script and add tool profile generation

* Now using actual tools specified in the operation.

* support mouse wheel and freecad-style 3d navigation

* Support accuracy gauge

* remove endsimulation reference

* show simulation speed indicator

* apply clang-format

* apply changes suggested by code review

* gui items are loaded via QT resource system instead of hard coded

* use vector instead of pointer to pass tool profile points

* Fix some more formatting errors.
