This does some long-overdue refactoring of the spaghetti code that grew in the GLFW embedding to begin providing a clearer separation between the engine and the window. It is now possible to register plugins, and run the runloop, on a headless engine, which makes headless mode much more usable. This is useful in some automated testing environments.

There is more refactoring that should be done in the future, but this is a good incremental point to stop as the PR is already large, and it provides useful new functionality as-is.

I eyeballed the entire patch but did not pay close attention to the event loop task heap management assuming you just moved it around. Happy to look closer if needed.

That's correct; the new base class is just most of the existing logic hoisted out of the GLFW-specific version.
