Going through the extension policy service rather than using WebExtensionPolicy objects directly adds a lot of unnecessary overhead to common operations on extension principals, and also makes the code more complicated than it needs to be. We also use weak references to policy objects here, since principals should ideally lose as much of their elevated privileges as possible once the extension instance that created them has been destroyed (which is something we couldn't handle easily when we simply tracked ID strings).
