Rewrite phosphor

This has been a long-awaited task, the code has been accumulating small
changes for a while now. This commit consolidates all these changes in
order to make the code more readable and maintainable for the future.

Notable changes:
- Remove the concept of a ProgramController
- Remove all of the dead OpenGL stub code
- Update winit to version 28.1, from 27.4
- Use softbuffer for writing pixels to the native display server
