They're now qfv_* and shared within the vulkan renderer. qfv_z_up cannot be shared across renderers as they have their own ideas for the world frame. qfv_box_rotations currently can't be shared across renderers because if the Y-axis flip and the way it's handled, but sharing should be achievable by modifying the other renderers to handle the sides correctly (glsl and gl need to do lookups for the side enums, sw just needs to be shown which way is up).
