Expose the "restart on exit" OS functionality

Browse source 
This can be used to restart a project with specific command line arguments
applied. This can work in tandem with `OS.get_cmdline_args()` to restart
with the same command line arguments as used to originally run the project.

Example use cases:

- Restart to apply an user setting change that requires a restart to work.
- Restart with a Godot command line argument to change the video driver,
  audio driver, etc.
