Restructure library dependencies and naming convention

[MStachowicz]

Having moved over to a 'true' ECS, there are many areas of code needing cleanup. The below list is an extensive collection of changes which should make the code much simpler.

• Remove Interface library
• Rename OpenGLAPI to OpenGL
• Move GLFWInput to Input library
• Move OpenGL related classes into "namespace OpenGL" and rename (e.g. OpenGLWindow - > OpenGL::Window
  • OpenGLRenderer
  • OpenGLWindow
  • Shader
• MoveTexture into Data namespace
• Move TextureManager and MeshManager into Manager namespace
• Move subscribing to ECS inside the OpenGL::Renderer constructor
• Move Camera to Data
• Rename namespace util to Utility
• Consolidate Utility libraries into the Utility lib
  • Logger
  • FileSystem
  • JobSystem
• Put all utility classes inside the Utility namespace
• Remove Types.hpp?
• Rename Managers to Systems
• Move Input into Systems namespace
• Add a SceneSystem
• Move Renderer scene construction into the SceneSystem
• Move OpenGL folder into source root
• Move OpenGLRenderer up into application
• Rename Renderer to Editor
• Put Editor into UI namespace?
• Add Platform lib abstracts away getting a platform specific window and input listener.
  • Window class
  • Input class -
    Window and input are tightly coupled (in GLFW anyway) so a propesed API is:
    Platform::Window::hasActionBeenRequested(Action)
• Remove InputSystem usage of ImGui for mouse
