This is adapted from Bighead's code that was posted at https://forums.dolphin-emu.org/Thread-dolphin-custom-texture-mipmaps?pid=460867#pid460867 In master, custom textures are never treated as having arbitrary mipmaps, so we need either a change like this or a change that makes us apply the arbitrary mipmap heuristic even when a custom texture is used.
