so there is already an Enzyme Autodiff Type interface, which should have a method for batching (and if not that would probably be the right place for this)

in a separate different PR, it may be worthwhile switching getShadowType and the likes to take an ArrayRef<int64_t> indices to batch on (@jumerckx did something similar when adding batched differentiation broadcast earlier)
