CrossPlatform GLFW Native Macro Config in CMake

- The GLFW_NATIVE macros are required for surface creation in the
  respective systems.
- Currently it was hard-coded for windows only.
- Added the required macros for linux and macos to remove the error that
  was in the Logs for vk_surface not created
- Also added the __externals folder to gitignore so that it is not
  detected. Useful when switching branches and experimenting between the
  older and this version.
