Revamped joystick locking
This makes the joystick locking more robust by holding the lock while updating joysticks. The lock should be held when calling any SDL joystick function on a different thread than the one calling SDL_PumpEvents() and SDL_JoystickUpdate(). It is now possible to hold the lock while reinitializing the joystick subsystem, however any open joysticks will become invalid and potentially cause crashes if used afterwards. Fixes https://github.com/libsdl-org/SDL/issues/6063
