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

-// About Desktop OpenGL function loaders:
-//  Modern Desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
-//  Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).
-//  You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
-
 // About GLSL version:
 //  The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
 //  On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
