Although we can support vulkan multiplane images, cuda lacks any such support, and so cannot natively import such images for interop. It's possible that we can do separate exports for each plane in the image and have it work, but for now, we can selectively disable multiplane when we know that we'll be consuming cuda frames. As a reminder, even though cuda is the frame source, interop is one way so the vulkan images have to be imported to cuda before we copy the frame contents over. This logic here is slightly more complex than I'd like but you can't just set the flag blindly, as it will cause hwframes ctx creation to fail if the format is packed or if it's planar rgb. Oh well.
