Fix build errors and update all dependencies to latest version

- Fixed doctest executable not compiling
- Fixed class accessibility error in Workflow_Main.cpp
- Fixed selection of OpenGL loader in imgui OpenGL 2 & 3 backends
  - All loading is handled in our code now, the imgui_*_backend.cpp files are instructed to do nothing
